Cold rolled S355K2W steel plate sheet thickness mm

S355K2W steel plate,The company has superior geographical location and convenient transportation. After more than 20 years of market trials and tribulations, from small to large, from weak to strong, in order to meet the needs of customer extension development, the company expanded the deep processing services of cutting steel pieces. Now we have built a business system integrating steel plate, steel plate cutting and steel deep processing. The company provides one-stop solution for customers with lower price, higher quality and faster response speed.

S355K2W steel plate,At present, China's wear-resistant steel plate grades are divided into six levels, namely NM300, NM360, NM400, NM450, NM500, NM550 and NM600. The wear-resistant steel grade adopts the combination of Chinese NM of wear resistance meaning and Brinell hardness (HB) value. For example: NM500, NM is the first universal parent of Chinese "wear resistance", "500" is Brinell hardness value. NM series wear-resistant steel has good wear resistance, which greatly reduces the loss and use cost.

After quenching and tempering, 40Cr alloy steel plate and sheet have good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity. The hardenability of steel is good. It can be hardened to Ф28 ～ 60mm during water quenching and Ф15 ～ 40mm during oil quenching. In addition to quenching and tempering, this steel is also suitable for cyanidation and induction hardening. The cutting performance is better. When the hardness is HB174 ～ 229, the relative cutting workability is 60%. 40Cr alloy steel is suitable for making medium-sized plastic molds.

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.

The Philiphine customer is our old customer, and they are engaged in offshore oilfield resources drilling projects. Thus they have regular steel demands. They ordered 1008 tons API 5L grade B ERW pipes and Q345B seamless pipes from us in April 2018. And told us that is a regular demand almost every two month. Since our first success cooperation, we have cooperated with each other regularly. And they also bring us new opportunities and signification in Philippians market.
