The company adheres to the customer philosophy of "customer first, pursuit of excellence". With the service tenet of "low price, excellent quality, fast transportation and constant commitment", we are committed to providing cold forming S355MC high-strength steel high quality and timely steel products and services for steel users all over the world. And created a good customer reputation. The main products of the company are section steel, steel pipe, thin plate, rolling plate, medium and thick plate, etc.

EH500 steel plates and EH550 steel plates are both ultra-high-strength structural steel plates for ships and oceans. The addition of microalloying elements can not only improve the strength, compensate for the strength loss caused by the reduction of carbon equivalent, but also improve the welding performance, mechanical properties and process performance of the steel cold forming S355MC high-strength steel. Due to the use environment requirements of EH500 steel plate and EH550 steel plate, it can meet the requirements of high strength, high toughness, high welding performance, and thickness direction performance.

Compared with cold forming S355MC high-strength steel, pressure vessel and boiler steel plates have such advantages: The pressure vessel and boiler steel should be pure, and the fracture structure of the boiler steel plate should be uniform without cracks and inclusions. Besides, the strain aging sensitivity is small, and the strain aging impact value of the pressure vessel and boiler steel plate is required to be no less than 50% of the non-aging impact value. That is why pressure vessel and boiler steel plate is first choice for fabricating pressure vessels and boilers, while cold forming S355MC high-strength steel is not.

When phosphorus, copper, chromium, nickel and other trace elements are added to the steel, cold forming S355MC high-strength steel, a dense and strong adhesive protective film will be formed on the steel surface, which will prevent the corrosion from spreading and developing inward, and protect the substrate under the rust layer, so as to slow down the corrosion rate. The amorphous spinel oxide layer of about 50 μ m ~ 100 μ m thickness formed between the rust layer and the substrate is compact and has good adhesion with the substrate metal.

2020 October stock cold forming S355MC high-strength steel product: 8*1800*10950, 16*2150*10950, 70*2270*7350, 6*2200*10000, 20*3200*4400, 20*2280*5800, 20*2100*10800, 70*2270*7000, 12*2050*5100, 20*3200*4400, 12*2000*11850, 14*2940*9600, 20*2150*10000, 70*2260*7700, 6*1950*10000, 12*2000*11850, 6*2200*10000, 14*2510*10950, 16*2150*10000, 70*2260*7240, 20*3200*4400, 6*2200*10000,20*2100*7000, 12*2500*8000, 20*2100*10750, 35*2200*6800, 12*2000*11850, 20*2100*7000, 31.2*2950*9380.
