ASTM A606 - SSAB high-strength steel

The ASTM A606 specification is the Standard Steel Specification for High-Strength, Low-Alloy, Hot Rolled and Cold Rolled Sheet and Strip Steel with Improved Atmospheric Corrosion Resistance for use in structural and other applications. A606 Type 4 steel has a minimum corrosion-resistance index of 6.0 based upon ASTM Guide G101. Boron steel - SSABBoron Steel. 15B30 is a carbon-boron steel produced in accordance with the American Iron and Steel Institute (AISI) and the Society of Automotive Engineers (SAE) chemical composition limits. 15B30 is a carbon steel with boron added to enhance the hardenability, strength and wear resistance compared to plain carbon steels of the same carbon content.

Docol PHS 1800 press hardening steel - SSAB

Hardenable boron steel for the automotive industry Docol® PHS 1800 is cold rolled and alloyed with a small percentage of boron to improve hardenability. This steel is specially developed for parts and components that are manufactured by both direct and indirect hot stamping.

Hot and cold rolled, sheets, plates and coils, steel tubes and profiles, steel piles and more. HSLA Steel Plate High Strength Low Alloy Kloeckner There are many different types of HSLA steel plate:Weathering steels have better corrosion resistance. Control-rolled steels are hot-rolled steels with a deformed austenite structure that, when cooled, turns into a fine equiaxed ferrite structure; Pearlite-reduced steels are steels with low levels of caron that lead to little to no pearlite.

Fundamentals of Dual-Phase Steels, pages 199220 Molybdenum alloying in high-performance flat-rolled steel Jan 09, 2020 · This steel is mostly produced as hot-rolled strip for spiral welded pipe. However, hot-rolled plate is used for longitudinal welded pipe when particularly heavy wall gage is needed. Due to toughness requirements, a carbon content of 0.04%0.06% and a homogeneous, fine-grained acicular ferritic microstructure is preferred .

Simulation of hot-rolled dual-phase weathering steel Dual phase weathering (DP-weathering) steels were developed by inter-critical annealing treatments from a commercial hot-rolled weathering steel. Simulation of hot-rolled dual-phase weathering steel Nov 01, 2005 · A dual-phase weathering steel that has both the excellent atmospheric corrosion resistance of normal weathering steel and the favorable comprehensive mechanical behavior and properties of a dual-phase steel can satisfy these requirements. Dual-phase steels are produced by either of two methods. One involves intercritical annealing.

Dual phase weathering (DP-weathering) steels were developed by inter-critical annealing treatments from a commercial hot-rolled weathering steel. The effects of Direct Hot Rolled Dual Phase Weathering SteelNew alloying concepts are proposed to develop hot-rolled weathering-dual phase steels that combine good strength-ductility balance and enhanced atmospheric corrosion resistance. The proposed concepts comprise mainly the alloying elements that improve the atmospheric corrosion resistance (Cu, Ni, P and Cr) and those that facilitate the
