WorldAutoSteel Guidelines for AHSS shed light on

The most widely available and widely used high-strength,low-alloy (HSLA) steel is 350/450 (350 MPa minimum yield strength/450-MPa minimum tensile strength).It is also known as HSLA 50,because the minimum yield strength converts to 50 KSI.The typical n-value for HSLA 350/450 is around 0.17.US4067756A - High strength,high ductility low carbon A high strength,high ductility low carbon steel consisting essentially of iron,0.05-0.15 wt% carbon,and 1-3 wt% silicon.Minor amounts of other constituents may be present.The steel is characterized by a duplex ferrite-martensite microstructure in a fibrous morphology.The microstructure is developed by heat treatment consisting of initial austenitizing treatment followed by annealing in Three generations of advanced high-strength steels for High-strength,low-alloy (HSLA) steels are CMn steels strengthened with the addition of a microalloying amount of titanium,vanadium,or niobium.These steels,with a tensile strength up to 800 MPa (115,000 PSI),still can be press formed (see Figure 2).HSLA was one of the first com-monly used HSS in the automotive industry in the 1990s.These

Tensile,Yield and Elongation Fisk Alloy

Elongation in wire can be measured and is reported over many different gauge lengths (2 to 60 inches) although the most common ones are 2 and 10 inches (50mm-250mm).Since elongation depends on the testing gauge length,when reporting elongation,the gauge length must also be reported (the longer the gauge length,the lower the measured Some results are removed in response to a notice of local law requirement.For more information,please see here.Previous123456NextPractical Maintenance Blog Archive Classification of Classification of plain carbon steels,low alloy steels,high strength low alloy (HSLA) steels and a variety of other low alloy steels mainly as per AISI/SAE method (and ASTM system where appropriate) up to 0.30 percent carbon Medium-carbon steels 0.30 to 0.60 percent carbon Total elongation (in 50 mm,or 2 in.) 21% min Some results are removed in response to a notice of local law requirement.For more information,please see here.12345NextTensile,Yield and Elongation Fisk AlloyElongation in wire can be measured and is reported over many different gauge lengths (2 to 60 inches) although the most common ones are 2 and 10 inches (50mm-250mm).Since elongation depends on the testing gauge length,when reporting elongation,the gauge length must also be reported (the longer the gauge length,the lower the measured
