What is the difference between S355ML grade and A36 metals?

In production and operation, the company always attaches great importance to product S355ML grade quality. Product quality is stable, performance index is superior, after-sales service is in place, the company's products have been exported to the United States, Southeast Asia, Africa, the Middle East and other countries and regions, occupying a large part of the overseas market S355ML grade. And a large number of famous enterprises at home and abroad have formed a solid strategic partnership with the company.

The S355ML grade weathering steel plates are our main products, which are also called weather resistant steel plates, corten steel plates, atmosphere corrosion resistant steel plate, anti-corrosion plates, etc. The main recognized standards for weathering steel plates are ASTM CORTEN, ASTM A588/A588M, ASME SA588/SA588M, EN 10025-5, EN 10155, TBT 1979, GBT 4171, JIS G 3114, JIS G3125, ASTM A242/A242M, etc. Our typical weathering steel grades are Corten A, A588 grade B, S355J2WP, S355J0WP, 09CuPCrNi-A, 05CuPCrNi, Q355NH, SPA-H, A242 type 1, etc.

Weather resistant steel, as a new generation of advanced steel materials, has atmospheric corrosion resistance 2 to 5 times that of ordinary carbon steel. The longer it is used, the more prominent the corrosion resistance. Because it has the characteristics of rust resistance, no coating, thinning and consumption reduction, labor saving and energy saving, weather resistant steel can be applied to steel structures used in buildings, vehicles, bridges, towers and other long-term exposure to the atmosphere, S355ML grade and can also be used to manufacture containers and railway Structural components such as vehicles, oil derricks, seaport buildings, and oil platforms.

The fake and inferior S355ML grade, steel plates have no metallic luster and are light red or similar to pig iron for two reasons. 1. Its blank is adobe. 2. The rolling temperature of counterfeit and inferior materials is not standard, and their steel temperature is visually inspected. In this way, rolling cannot be carried out in the specified austenite area, and the performance of the steel plate will naturally not meet the standard.

As per JIS G3101 standard, the Carbon (C), Silicon (Si) and Manganese (Mn) content of SS400 steel plate are not controlled. Phosphorus (P) content of S355ML grade, JIS SS400 steel plate is 0.050% Max and Sulphur (S) content is 0.050% Max. The SS400 steel melting point is 1430 Degree Celsius, Brinell Hardness is 160HB, density is 7.85g/cm3, Young’s Modulus is 190-210Gpa. The strength and elongation of JIS SS400 steel plate varies with thickness. Generally, the tensile strength of SS400 steel plate is 400-510 Mpa. Elongation is above 21%. Yield strength ≥245Mpa for thickness≤16mm. When the JIS SS400 steel plate is thciker than 100mm, the yield strength shall not less than 205Mpa.

We have our own factory, including the production and manufacturing of steel pipes, with a special S355ML grade steel pipe manufacturer and storage warehouse. Welcome to visit our factory, we will provide customers with high quality products that meet the requirements. And has the perfect S355ML grade after-sale service guarantee system, lets the customer save the worry and the labor.

Our company will accept the product quality objection registration record, pass it to the S355ML grade production unit and relevant departments, and timely coordinate the supervision of product S355ML grade quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
