What are the top 5 ASTM A242 HIC tested plate mills in Iran

Standing at a new historical starting point, we adapt to the requirements of supply side ASTM A242 HIC tested plate structural reform, adhere to the overall strategy of "innovation driven, quality leading, quality improving and efficiency increasing, transformation and development", and constantly improve the development concept and development level with a forward-looking vision and grand vision. Now we have been ranked the International leading ASTM A242 HIC tested plate steel materials supplier.

Steel plate is divided into rolling, hot rolling and cold rolling. The width of the thin plate is 500 ~ 1500 mm; the width of the thick plate is 600 ~ 3000 mm. Thin plates are classified according to steel types, including ordinary steel, steel, alloy steel, spring steel, stainless steel, tool steel, heat-resistant steel, ASTM A242 HIC tested plate, bearing steel, etc .; according to use, there are ship plates, pressure vessel plates, atmospheric corrosion-resistant steel plates, bulletproof steel plate.

We have full ranges of gas cylinder steels, not only GB standard gas cylinder steel, but also JIG standard and EN standard materials. Such as SG255, SG295, HP265, P245NB, etc. The MOQ is 200 tons. For the gas cylinder steel coil, we can do ASTM A242 HIC tested plate further processing in our processing center and provide you gas cylinder steel plates. And we can punch steel discs for your convenient use.

ASTM A242 HIC tested plate, Q345B low alloy steel plate composition:
1) Low carbon: Due to the high requirements for toughness, weldability and cold forming properties, its carbon content does not exceed 0.20%;
2) Add manganese-based alloying elements;
3) Adding auxiliary elements such as niobium, titanium or vanadium: a small amount of niobium, titanium or vanadium forms fine carbides or carbonitrides in the Q345B steel, which is conducive to obtaining fine ferrite grains and improving the strength and toughness of the steel;
In addition, adding a small amount of copper (≤0.4%) and phosphorus (about 0.1%) can improve the corrosion resistance. Adding a small amount of rare earth elements can desulfurize and degas, purify steel, improve toughness and process performance.

According to GBT3077, 42CrMo steel chemical composition should be within the range (%): 42CrMo carbon content is 0.38-0.45 (C), Silicon content is 0.17-0.37 (Si), Manganese content is 0.50-0.80 (Mn), Chrome content is 0.90-1.20 (Cr), Molybdenum content is 0.15-0.25 (Mo). The high Cr content contrivutes to high strength of 42CrMo steel, with min. yield strength of 930 Mpa, and min. tensile strength of 1080 Mpa. The common heat treatment for ASTM A242 HIC tested plate, 42CrMo steel is quenching and tempering.
