Hot Rolled Steel Plate 1/2" x 8" x 8" JIS carbon steel SM490B CS plate Carbon Steel

With high-quality steel and professional services, we have won international praise in infrastructure, shipbuilding, oil and other industries, and gradually grow into a bright star in the steel export industry, while winning unanimous praise from foreign customers It has laid a foundation for the development of our steel market and improved the control of steel plate production quality,JIS carbon steel SM490B CS plate.

Q420B material is a low-alloy high-strength structural steel. JIS carbon steel SM490B CS plate, Q420 is not high-strength steel, it is still low-carbon steel. Its tensile strength has been improved a bit. The tensile strength of Q235 steel is 235MPa, and the tensile strength of Q420B steel is 420MPa. Q420B low alloy steel has high strength and good fatigue resistance; high toughness and low brittle transition temperature; good Cold forming performance and welding performance; has good corrosion resistance and certain wear resistance.

JIS carbon steel SM490B CS plate,42CrMo steel plate is an ultra-high strength steel plate, which is widely used in machinery manufacturing steel The steel is suitable for manufacturing large and medium-sized plastic molds that require certain strength and toughness 42CrMo steel has high strength and toughness, good hardenability, no obvious temper brittleness, high fatigue limit and multiple impact resistance after quenching and tempering, and good low temperature impact toughness,JIS carbon steel SM490B CS plate.

JIS carbon steel SM490B CS plate,The advantage of hot-rolled stainless steel plate is that it can eliminate the damage caused by metal structure in the process of ingot casting to a certain extent, eliminate some tiny defects in the structure, refine the grains of stainless steel material, promote the structure of steel closer, and improve the performance of the material as a whole. This kind of lifting is mainly manifested in the rolling direction, which can make the steel no longer isotropic to some extent, and some defects such as bubbles, cracks and looseness formed during pouring can be eliminated under high temperature or high pressure.

Mechanical properties of 45# steel high-quality carbon structural steel: Tensile strength σb (MPa): ≥600, yield strength σs (MPa): ≥355, elongation δ5 (%): ≥16, section shrinkage ψ (%): ≥40, impact energy Akv (J): ≥39 45# steel impact toughness value αkv (J / cm2): ≥49 (5), hardness: unheated, ≤229HB; annealed steel, ≤197HB 45# steel chemical composition % (Carbon: 042 to 050, Silicon: ≤040, Manganese: 050 to 080, Sulfur: ≤0045, Phosphorus: ≤0045, Chromium: ≤040, Nickel: ≤040, Molybdenum: ≤010),JIS carbon steel SM490B CS plate.

JIS carbon steel SM490B CS plate,We have a professional after-sales service team, the company has developed a clear service process and service standards, after-sales service team members strictly perform after-sales procedures, comply with service standards.
