Our company's JIS G 3114 SMA400AW, SMA400BW, SMA400CW power boilers, heating furnaces of double bars, double high lines and medium and thick plates all adopt heat storage technology, which can fully use blast furnace gas; the ladle baking, Maerz active lime kiln and medium and thick plate heat treatment furnace all burn converter gas, which can improve the JIS G 3114 SMA400AW, SMA400BW, SMA400CW utilization rate of secondary energy and realize negative energy steelmaking in steelmaking process.
The hardness value of NM600 wear-resistant steel plate reaches 600 HBW, and it is generally used in extremely severe wear occasions, and mainly used to replace cast steel, chromium alloy cast iron and surface hardening metal JIS G 3114 SMA400AW, SMA400BW, SMA400CW. Although the hardness of NM600 wear-resistant steel plate is very high, we can machine, weld and cut it. Although the hardness of NM600 wear-resistant steel plate is very high, it still has high impact toughness.
Heat treatment advantages of JIS G 3114 SMA400AW, SMA400BW, SMA400CW, SA516 Gr 70 pressure vessel steel: 1) SA516 Gr 70 pressure vessel steel quenching: The hardness of SA516 Gr 70 pressure vessel steel is increased, but the toughness is decreased. 2) SA516 Gr 70 pressure vessel steel normalizing: Improve strength and toughness. 3) SA516 Gr 70 pressure vessel steel annealing: Eliminate quenching effect, eliminate stress, uniform composition. 4) SA516 Gr 70 pressure vessel steel tempering: Uniform composition, slightly reduce hardness, greatly improve toughness.
Composition characteristics of low alloy structural steel, JIS G 3114 SMA400AW, SMA400BW, SMA400CW: (1) Low carbon: the carbon content of low alloy structural steel is less than 0.20% due to the high requirements of toughness, weldability and cold formability. (2) The alloy elements such as manganese are added. (3) The addition of Nb, Ti or V and other auxiliary elements: a small amount of Nb, Ti or V forms fine carbides or carbonitrides in the steel, which is beneficial to obtain fine ferrite grains and improve the strength and toughness of low alloy structural steel. In addition, adding a small amount of copper (≤ 0.4%) and phosphorus (about 0.1%) can improve the corrosion resistance. The addition of a small amount of rare earth elements can remove sulfur and gas, purify the steel, and improve the toughness and process performance of low alloy structural steel.
JIS G 3114 SMA400AW, SMA400BW, SMA400CW, S355JR is a European standard low alloy high strength structural steel, which is in accordance with EN10025-2. The hardness of S355JR steel is 70-80B, and the yield strength of S355JR steel is 355MPa. JR stands for quality level, equivalent to level B in ChinaChemical composition of S355JR steel: C: < 0.22; Si: < 0.55; Mn: < 1.60; P: < 0.025; S: < 0.025S355JR steel is equivalent to Q345B in China.
