What is the astm a537 class 1 yield strength price export to Morocco

In recent years, in line with the development trend of iron and astm a537 class 1 yield strength steel industry at home and abroad, we have accelerated the transformation of development mode, promoted structural adjustment, and formed a rich product series of medium and thick plates, hot rolled steel coils, profiles, steel pipes, etc., which astm a537 class 1 yield strength are widely used in automobiles, long-span bridges, railways, machinery, ocean and so on fields. Meanwhile, we also provide deep processing for the steel materials.

S50C steel plate is a high-quality high-quality medium carbon steel. S stands for steel, which means iron, and 50 stands for carbon content of 0.50%. C represents carbon steel, which means that S50C is a carbon steel with a carbon content of 0.50%.
Mechanical properties of S50C steel plate:
Tensile strength σb (MPa): ≥630 (64); Yield strength σs (MPa): ≥375 (38); Elongation δ5 (%): ≥14; Reduction of area ψ (%): ≥40; Impact Work Akv (J): ≥31(4); Impact toughness value αkv (J/cm2): ≥39(4)
Hardness: unheated, ≤241HB; annealed steel, ≤207HB

NM series wear-resistant steel plates have uniform hardness, avoid the local fracture phenomenon caused by uneven hardness. Compared with ordinary steel plate, NM360 steel plate has wear resistance of not less than twice, NM400 steel plate has wear resistance of not less than 2.5 times, and NM550 steel plate has wear resistance of not less than 4 times. The wear-resistant steel plate combines the characteristics of high strength, high hardness, weldability and easy bending.

The final heat treatment of quenched and tempered alloy steel, astm a537 class 1 yield strength is quenching and high temperature tempering. The hardenability of quenched and tempered alloy steel is high, and oil is generally used. When the hardenability is very high, it can even be air cooled, which can reduce the defects of heat treatment. The final properties of quenched and tempered alloy steel depend on tempering temperature. Generally, it is tempered at 500 ℃ - 650 ℃. The required properties can be obtained by selecting tempering temperature. In order to prevent the second kind of temper brittleness, fast cooling (water cooling or oil cooling) after tempering is beneficial to the improvement of toughness.

S355J2G3 is low alloy high strength structural steel, and it is roughly equivalent to GB Q345D.S355J2G3 is a European standard steel with composition of C ≤ 0.20, Si ≤ 0.55, Mn ≤ 1.60, P ≤ 0.035, S ≤ 0.035. The meaning of J2G3 indicates that the delivery state of S355J2G3 steel is normalized, the impact energy at - 20 ℃ is 27J. G3 and G4 indicate the deoxidization mode. astm a537 class 1 yield strength, S355J2G3 steel is semi killed steel, S355J2G4 steel is fully killed steel.
