6mm thick S420ML carbon steel plate sheet

The commonly S420ML carbon steel plate sheet steels used to manufacture pressure parts of boilers mainly include low carbon steel, low alloy structural steel, low alloy heat-resistant steel, austenitic stainless heat-resistant steel and martensitic heat-resistant steel, etc. According to profiles, these boiler steels can be divided into boiler steel plates and boiler steel pipes. Our main S420ML carbon steel plate sheet boiler steel materials are as follows: A516 Gr 70, A537 class 1 , 16Mo3, Q345R, A204 grade B, A285C, ASTM A387, P355GH and so on.

The company specializes in the research and development, production and sales of S420ML carbon steel plate sheet seamless pipes, longitudinally welded pipes, large-diameter welded pipes, API 5L welded pipes, spiral welded pipes, and large-diameter thick-walled straight seam steel pipes. The company has S420ML carbon steel plate sheet five production lines in three major production workshops: large-diameter longitudinally welded pipe production workshop,S420ML carbon steel plate sheet rolled steel pipe production workshop, and thermally expanded steel pipe production workshop, with an annual production capacity of more than 100,000 tons.

The wear-resistant plate has the main advantages of high strength and hardness, good toughness, S420ML carbon steel plate sheet high tensile strength, good material wear-resistance, long service life and low cost. In order to verify the wear-resistant life of the high wear-resistant composite steel plate applied in the field, the comparative industrial test of S420ML carbon steel plate sheet wear-resistant with the ordinary carbon plate was carried out on the reclaimer of Jigang raw material plant, and the effect is good.

The effect of nitrogen on steel performance is similar to that of carbon and phosphorus. With the increase of S420ML carbon steel plate sheet nitrogen content, the strength of steel can be improved, plasticity especially toughness can be significantly reduced, weldability becomes worse, and cold brittleness is intensified. Nitrogen with aluminum, niobium, vanadium and other elements can reduce its adverse effects, improve the performance of S420ML carbon steel plate sheet steel, can be used as an alloying element of low alloy steel.

After-sales service team is a key department to test the steel quality. Product quality is always the foundation of our survival and development. The company's full inspection from raw materials to finished products; and implements standardized, scientific, and strict internal quality control and management systems in accordance with the process flow during the production process; products can only leave the factory if qualified, and follow-up problem solving systems are implemented in after-sales services to guarantee the customers’ interest.
