Type 309 and 310 [12] are used in high temperature applications greater than 800 °C (1,500 °F). Note: ferritic stainless steels do not retain strength at elevated temperatures and are not used when strength is required.
Precipitation hardening, also called age hardening or particle hardening, is a heat treatment technique used to increase the yield strength of malleable materials, including most structural alloys of aluminium, magnesium, nickel, titanium, and some steels, stainless steels, and duplex stainless steel. In superalloys, it is known to cause yield ...
[3] 0.2% proof and ultimate tensile strength of the Fe–55Mn–3Al–3Si wt% TWIP steel as a function of the test temperature; strain rate ε=10 −4.s −1. [ 3 ] Austenitic steels are used widely in many applications because of their excellent strength and ductility combined with good wear and corrosion resistance.
Type 310 310S— is a highly alloyed austenitic stainless steel used for high temperature application. The high chromium and nickel content give the steel excellent oxidation resistance as well as high strength at high temperature. This grade is also very ductile, and has good weldability enabling its widespread usage in many applications. [7]
SAE Type 630 stainless steel (more commonly known as 17-4 PH, or simply 17-4; also known as UNS S17400) is a grade of martensitic precipitation hardened stainless steel. It contains approximately 15–17.5% chromium and 3–5% nickel, as well as 3–5% copper. [1] The name comes from the chemical makeup which is approximately 17% chromium and 4 ...
Steel with a high carbon content will reach a much harder state than steel with a low carbon content. Likewise, tempering high-carbon steel to a certain temperature will produce steel that is considerably harder than low-carbon steel that is tempered at the same temperature. The amount of time held at the tempering temperature also has an effect.
Minimum Yield Strength: B: Steel for reinforced concrete: Characteristic Yield Case: R: Steel for rail use: Minimum Yield Case: H: High Tensile Strength Flat products: Minimum Yield Case: If followed by T then the given mechanical property is minimum tensile strength D: Flat Products for Cold Forming: Followed by C, D or X and two numbers ...
The ultimate tensile strength of a material is an intensive property; therefore its value does not depend on the size of the test specimen.However, depending on the material, it may be dependent on other factors, such as the preparation of the specimen, the presence or otherwise of surface defects, and the temperature of the test environment and material.
