Preventing future problems and troubleshooting existing problems in today's stamping plants requires greater stamping process knowledge. The link between inputs and outputs isn't as clear as many think, increasing the need for detailed understanding of the variables involved. This course discusses the key inputs and outputs associated with sheet metal stamping, including important elements for controlling the process and making it more robust. The course reviews sheet metal characteristics and their application, especially from a formability standpoint, using many automotive-related examples.

The Global Brake Safety Council sees an increase in disc brake pads that are prematurely replaced before the end of the friction lining life cycle, due to: Rust related issues such as separation of friction lining from the disc brake shoe Fluctuation in critical dimensions A leading cause for both issues is the use of mill scale steel, or ‘black steel’ (non-pickled and oiled). In the North American aftermarket, as there are little or no steel specifications for disc brake shoes, black steel is increasingly used. GBSC conducted research of discarded disc brake pads from job-shops and engaged in discussions with metallurgists, major pad manufacturers and OE brake foundation engineers to identify root causes of premature pad replacement and the effects of black steel used for disc brake shoe manufacturing. Mill scale is embedded in and around the bond line of the friction lining and the disc brake shoe, causing a weaker bond, susceptible to rust jacking.

Abstract Over the last few years, many aircraft production lines have seen their production rate increase. In some cases, to avoid bottlenecks in the assembly lines, the productivity of processes needs to be improved while keeping existing machine-tools. In this context, the case of drilling machine-tools tends to require particular attention, especially when multi-material parts are drilled. In such instances, the Vibration Assisted Drilling (VAD) process can be a way to improve productivity and reliability while keeping quality standards. This article presents a case of a drilling/countersinking process for stainless steel and titanium stack parts. Firstly, the article assesses the feasibility and benefits of using Vibration Assisted Drilling and Countersinking with the current cutting-tools.

Abstract 15-5PH is a precipitation-hardening, martensitic stainless steel used for primary structural elements such as engine mounts where corrosion resistance, high strength, good fatigue and fracture toughness is required. The material composition is defined in AMS5659M. This alloy can be either Type 1 - vacuum arc remelt (VAR) or Type 2 - electro slag remelt (ESR) and is most commonly heat treated per SAE AMS-H-6875 or AMS2759/3 to condition H1025 (an ultimate tensile strength of 155 ksi [1070 MPa] minimum). Typically material handbooks have limited fatigue data and most data is only for Type 1. Therefore, the fatigue properties of 15-5PH H1025 stainless steel for both Type 1 and Type 2 were determined. The objective of the fatigue testing was to generate a family of S-N curves (maximum stress versus number of cycles to failure) for a series of stress ratios across the entire range of cycles to failure.

Advanced High Strength Steels (AHSS) are now commonly used in automotive body structural applications. The high strength of this grade classification is attractive to help reduce mass in the automotive body through reduction in thickness. Strength also supports improvements in safety requirements so that mass increases are minimized. In some specific grades of AHSS, energy absorption is possible in addition to the high strength. This course will review the definition and properties of AHSS and cover several common applications in automotive body structures.
This specification covers an aircraft-quality, low-alloy steel in the form of bars, forgings, mechanical tubing, and forging stock.
Driving EVs toward lower cost The race is on to reduce battery and electric-drive systems costs while improving efficiency. Seeking ways to make better computer crashes New models and simulations help improve safety as software and hardware provide more realism to iterate designs more quickly. Evaluating aluminum bonds Adhesively joined aluminum alloy sheets present challenges that steel-adhesive joints do not. Ford researchers present a modified technique to inspect Al-adhesive joints in lab and production environments. Leading the attack on engine pumping losses Cylinder deactivation delivers real-world fuel economy gains, helping vehicles to meet and exceed their sticker numbers. That's why the downsized/boosted guys now want it on their engines.

This SAE Standard specifies dimensions and requirements for single-wall steel tubing intended for use as high-pressure fuel injection pipes on a wide range of engines (Class A), and for fuel injection pump testing (Class B, Reference SAE J1418). Tubing shall be cold drawn, annealed or normalized, seamless tubing suitable for cold swaging, cold upsetting, and cold bending.
This procurement specification covers bolts and screws made from a low alloy, heat resistant steel of the type identified under the Unified Numbering System as UNS K14675, having UNJ profile threads. The following specification designations and their properties are covered: AS7459 195 ksi minimum ultimate tensile strength at room temperature; 145 ksi minimum ultimate tensile strength at 900 degrees F; 105 ksi stress rupture strength at 900 degrees F for 100 hours; 100 ksi tension to 10 ksi tension fatigue at room temperature; Protective treatment to be specificed on part drawing; AS7459-1 AS7459 part plated per AMS 2416, nickel-cadmium diffused plating; AS7495-2 195 ksi minimum ultimate tensile strength at room temperature; 117 ksi minimum ultimate shear strength at room temperature Protective treatment to be specified on part drawing; AS7495-3 AS7495-2 part plated per AMS 2416, nickel-cadmium diffused plating.

This specification has been declared "NONCURRENT " by the Aerospace Materials Division, SAE, as of December 2008. It is recommended, therefore, that this specification not be specified for new designs. "NONCURRENT " refers to those specifications which have previously been widely used and which may be required for production or processing of existing designs in the future. The Aerospace Materials Division, however, does not recommend these specifications for future use in new designs. NONCURRENT " specifications are available from SAE upon request.

This specification covers a corrosion-resistant steel in the form of welding wire.

This wire has beem used typically as filler metal gas-tungsten-arc and gas-metal-arc welding of low-alloy steels where response to heat treatment is required in the weld, but usage is not limited to such applications.

The SAE Standard covers normalized electric resistance welded flash controlled single-wall, carbon steel pressure tubing intended for use as pressure lines and in other applications requiring tubing of a quality suitable for cold forming, welding and brazing. Material produced to this specification should not be used for single flare applications due to the potential leak path that would be caused by the ID weld bead or scarfed region. Assumption of risks when using this material for single flare applications to be defined by agreement between the producer and tube purchaser. The grade of material produced to this specification is higher in carbon and manganese content than the grade of material specified in SAE J356 and is intended to service higher pressure applications than equivalent sizes of SAE J356. Due to the higher carbon and manganese content the forming characteristics of the finished tube are diminished versus the SAE J356 product.
The purpose of this SAE Aerospace Recommended Practice (ARP) is to provide the aerospace industry with recommendations concerning the minimization of stress corrosion cracking in wrought heat-treatable carbon and low alloy steels and in austenitic, precipitation hardenable, and martensitic corrosion-resistant steels and alloys. The detailed recommendations are based on laboratory and field experience and reflect those design practices and fabrication procedures which should avoid in-service stress corrosion cracking.
This SAE Aerospace Standard (AS) establishes requirements for the manufacture and certification of tool steel rings for magnetic particle inspection.
