AHSS 101 - The Evolving Use of Advanced High Strength

other materials. Conventional low- to high-strength steels include IF (interstitial free), BH (bake hardened), and HSLA (high-strength low-alloy). These steels generally have yield strength of less than 550 MPa and ductility that decreases with increased strength. (More information about these steel types in Section 8.2.1.) Advanced High-Strength Steel (AHSS) Definitions As an example, DP 500/800 means dual-phase steel with 500 MPa minimum yield strength and 800 MPa minimum ultimate tensile strength. The ULSAB-AVC program first used this classification system. Metallurgy of AHSS. Manufacturers and users of steel products generally understand the fundamental metallurgy of conventional low- and high-strength steels.

BUYER'S GUIDE:High-Strength Steel - What's The Big Deal

A recent report by Markets and Markets says that the high-strength steel market is to grow by about 8% per year through 2021. By then, the market should be about 21 billion U.S. dollars globally. The report says that the automotive market is the number one user of high-strength steels and that Asia Pacific is the largest user by region. CN102134686A - Low-alloy wheel steel for railway wagons The invention discloses low-alloy wheel steel for railway wagons, which is characterized by comprising the following chemical components in percentage by weight:0.70-0.75% of C, 0.75-0.95% of Si, 0.75-0.90% of Mn, 0.15-0.25% of Ni, 0.25-0.35% of Cr, 0.015-0.030% of Als, P less than or equal to 0.010%, S less than or equal to 0.010% and the balance of Fe and unavoidable impurity elements. Carbon & High Strength Low Alloy (HSLA) Structural Steel Leeco ® Steel carries a deep inventory of carbon - or mild - steel plate as well as High Strength Low Alloy - or HSLA - steel plate. HSLA boasts a higher strength, lower weight and good machinability and ductility compared to conventional mild carbon steel grades. HSLA structural steels are manufactured to meet specific mechanical properties, such as hardness, strength, corrosion resistance

They are notHigh-Strength Low-Alloy Steels - ASM International HIGH-STRENGTH LOW-ALLOY (HSLA) STEELSHigh-strength low alloy (HSLA) or micro alloyed steels present a yield strength of 340-420 MPa and ultimate tensile strength of 410-510 MPa, while their uniform elongation ranges between 10 and 25%. High-Strength Low-Alloy Steels - ASM InternationalHigh-strength low-alloy steels include many standard and proprietary grades designed to provide specific desirable combinations of properties such as strength, toughness, formability, weld-ability, and atmospheric corrosion resistance. These steels are not consid-ered alloy steels, even though their desired properties are achieved by the

    High-strength steel:Strong, lightweight & cost effective

    Low weight pays off in reduced fuel consumption throughout the life span of the vehicle. And if something happens it is easier to repair a car made of high-strength steel. All workshops have experience of working with steel compared to cars made of new materials. Rails and Rail Steel IspatGuruMay 05, 2013 · So, the requirements from rail steel are to make the rails stronger and more wear and defect resistant, in order to minimize rail maintenance costs and maximize asset life. The increase in strength of the rail steel needed mainly to cater for the heavy axle loads. Rail steel of around 1,300 MPa to 1,400 MPa is now being used in large quantities. Special Issue "Mechanical Behavior of High-Strength Low For both steels, the yield strength (YS) monotonically increased with strain rates, whereas the values of ultimate tensile strength (UTS), uniform elongation (UE) and post-uniform elongation (PUE) were maintained stable at the low strain rate range (0.0010.1 s 1), followed by a significant increase with strain rate at high strain rate
