What does 4140 HTSR stand for?

What does 4140 HTSR stand for?

Heat Treated, Stress Relieved (HTSR) 4140 has been heat treated to reduce brittleness and relieve any stress fractures throughout the bar. This is done by heating the material just below a specific recrystallization temperature and held there for a fixed amount of time.

Is AISI 4140 a carbon steel?

AISI 4140 is versatile because of its simple chemistry and has the following composition: 0.40 % carbon and 0.85 % manganese which offers toughness and can be heat treated and hardened 0.1 % chromium adds to overall toughness but is not enough to be made into stainless steel.

Is 4140 and 4142 the same?

Both quenched and tempered SAE-AISI 4140 and SAE-AISI 4142 steel are iron alloys. Their average alloy composition is basically identical. For each property being compared, the top bar is quenched and tempered SAE-AISI 4140 and the bottom bar is SAE-AISI 4142 steel.

What can be found in AISI 4140 datasheet?

This page is mainly introduced the AISI 4140 Datasheet, including chemical information,mechanical properties, physical properties, mechanical properties, heat treatment, and Micro structure, etc. It also contains the use of AISI 4140,such as it is commonly used in bars, sheet,plates, steel coils, steel pipes,forged and other materials application.

What’s the tempering temperature of AISI 4140 steel?

AISI 4140 alloy steel is annealed at 872°C (1600°F) followed by slowly cooling in the furnace. AISI 4140 alloy steel can be tempered at 205 to 649°C (400 to 1200°F) depending upon the desired hardness level. The hardness of the steel can be increased if it has a lower tempering temperature.

What are the properties of SAE 4140 steel?

SAE AISI 4140 Alloy Steel SAE 4140 (AISI 4140 steel) is a Cr-Mo series (Chrome molybdenum series) low alloy steel, this material has high strength and hardenability, good toughness, small deformation during quenching, high creep strength and long-lasting strength at high temperature. 4140 Steel Uses
