A novel two-step intercritical annealing process was designed for an ultra-low carbon medium manganese steel plate. Excellent mechanical properties with yield strength of 590 MPa, tensile strength of 840 MPa, total elongation of 28.5% and high impact energy of 106 J at 80 °C were obtained.The microstructure comprised of ultra-fine grained ferrite and retained austenite together
BAOSTEEL GROUP New ProductsThis series of high strength steel is low carbon low alloy steel with good weldability, cold formability and high toughness at low temperature, which is widely used in the field of construction machinery, automobile structure and marine container industries.By switching from conventional steel to high strength steel, the designed thickness and structure weight can be obviously reduced.Attachment:product manual of high strength cold forming hot-rolled steel
An antiwear high-Cr cast steel used as antiwear material in pulverizing job contains such chemical components as C (1.2-2.5%), Si (less than 0.6%), Cr (11.5-13.5%), Mo (0.7-1.2%), Cu (0.5-1.0%), Mn (less than 0.6%), V (3.5-4.5%), Re (0.03-0.05%), S (less than 0.06%), P (less than 0.06%) and Fe (rest), and features high hardness and strength, better toughness, and long service life.
High-Strength Low-Alloy Steels - ASM International15% (max) with a minimum vanadium-to-nitrogen ratio of 4:1. (j) When silicon-killed steel is specified. (k) For plate under 40 mm (1.5 in.), manganese contents are 0.70 to 1.35% or up to 1.60% if carbon equivalents do not exceed 0.47%. For plate thicker than 40 mm (1 to 5 in.), ASTM A 841 specifies manganese contents of 1.00 to 1.60%.
High-Strength Structural and High-Strength Low-Alloy As-rolled carbon-manganese steels As-rolled high-strength low-alloy (HSLA) steels (which are also known as micro alloyed steels) Heat-treated (normalized or quenched and tempered) carbon steels Heat-treated low-alloy steels. These four types of steels have higher yield strengths than mild carbon steel in the as-hot-rolled condition.
Dec 06, 2019 · Introduction. In recent years, low carbon medium manganese steel has emerged as a competitive candidate of third-generation green vehicle steel, attracting significant attention because it has a good tradeoff between material cost and mechanical properties [1,2].Meanwhile, the idea of low carbon medium manganese was increasingly employed in design and manufacture of high strength

WO2014152767A1 - Low carbon-high manganese steel and A low carbon-high manganese steel sheet and process for manufacturing the sheet is provided. The process includes soaking a steel slab with a desired chemical composition within a temperature range of 1200-1350°C, followed by hot rolling of the slab into hot strip. The cold rolled sheet is continuously annealed within a temperature range of 730-850°C and temper rolled between 1.0-2.0%.
