4 1/4 inch plate nm400 material stock

The company attaches great importance to the value of iron and steel, constantly improving itself in terms of attitude, innovation, human resources, etc., integrating the value of iron and steel into the company's philosophy, showing the spirit of fighting for iron and steel, forging iron and steel enterprise, creating steel market, establishing iron and steel team, and attaching importance to the sustainable development of iron and steel industry, so as to make iron and steel our permanent cause,NM400 material., SS400 steel is one of the most commonly used hot rolled general structural steel. SS400 steel’s mechanical properties is yield strength more than 225-235MPa, tensile strength 360-510Mpa and 340-470Mpa. For SS400 steel, the C element content is 0.2% max, the Mn element content is 1.40% max, the P element content is 0.045% max, the S element content is 0.045% max.NM400 material,After a certain period of time, the steel products will reduce the toughness and increase the hardness, which is called aging effect. Generally, this effect is strongest at 200-300 ℃. The aging tendency of , low carbon steel (about 01% carbon content) is especially large, while high carbon steel and alloy steel containing molybdenum, barium or tungsten are not easy to produce aging For boiler steel plate, it is required that the reduction rate of impact initial property is not more than 50%, or the absolute value of impact initial property is not less than 3-35KGM / cm2,NM400 material.In March, the daily output of key iron and steel enterprises decreased on a month on month basis. In terms of enterprise inventory, in late March, the key statistics showed that the NM400 material steel inventory of iron and steel enterprises was 18067 million tons, a decrease of 3342 million tons or 156% compared with the highest inventory in early March, and an increase of 8534 million tons or 895% compared with the beginning of the year,NM400 material.Our quality control department will do inspection for details of the steel materials before delivery We would invite the customer side to attend the inspection together If they can not come, we will also take rich pictures for them to check Meanwhile, we will publish inspection report and send them the PDF version Besides, we accept any third party inspection such as SGS, BV, etc And our quality control department will support the third party to inspect the steel materials smoothly and try our best to deliver the qualified steel materials to customers earlier,NM400 material.In February, the European steel price index was 161.2 points, up 1.3 points on a month on month basis, up 0.8%; the euro zone manufacturing PMI was 49.2%, up 1.3 percentage points on a month on month basis. The manufacturing PMI of Germany, Italy, France and Spain were 48%, 48.7%, 49.8% and 50.4% respectively. This month, among the main steel products such as in the German market, the price of wire rod decreased slightly, the price of section steel remained stable, and other products continued to rise.
