Plain carbon steel JIS SM570 plates angle specification

Carbon steel mainly refers to the steel whose mechanical properties depend on the carbon content in the JIS SM570 plates steel, and generally does not add a lot of alloy elements, sometimes it is also called ordinary carbon steel. Carbon steel refers to iron carbon alloy with carbon content of WC less than 2%. In addition to carbon, carbon steel generally contains a small amount of silicon, manganese, sulfur and phosphorus. According to the content of phosphorus and sulfur, the carbon steel can be divided into ordinary carbon steel, high quality carbon JIS SM570 plates steel, high quality steel and super quality steel.

The company adheres to the service concept of "you give the order to me and I leave the satisfaction to you". Over the years, our JIS SM570 plates steel products are supplied in time, with reliable quality and perfect and thoughtful after-sales service. Meanwhile, we have huge JIS SM570 plates steel stocks all the year round. The company long-term pursues the principle of quality first, customer first, quality for survival, reputation for development, and perfect service to win the users.

In recent years, after the completion of large-scale, high-speed and automation of steel rolling technology and equipment in the world, the rapid development of JIS SM570 plates high-precision rolling technology with the goal of improving product quality, expanding varieties, saving energy and reducing consumption, and increasing benefits. For example, in 2013, Anshan Iron and Steel's 4300 mm rolling mill, Shagang's 5000 mm rolling mill and 3500 mm furnace coil rolling mill introduced foreign technology to further upgrade the company's JIS SM570 plates technical equipment.

Although JIS SM570 plates, low carbon steel has excellent plasticity, toughness and processing technology, its strength is low and its corrosion resistance is not strong enough. On the basis of ordinary low carbon steel, the low alloy structural steel with high strength, high toughness, good weldability and corrosion resistance can be obtained by adding a small amount of alloy elements and the total amount is less than 3%. Manganese is the main additive element in this kind of steel, and its content is about 1% ~ 1.6%.

When providing technical services on site, the after-sales personnel shall strictly abide by the safety rules and regulations of the construction site, consciously take safety protection measures (such as wearing safety helmet when entering the construction site), accept the supervision and management of the site; without permission on the construction site, they shall not dismantle, smear or damage any goods; the commissioning of contract goods shall be carried out under the supervision of the site supervisor If necessary, it shall be approved by the site supervisor or the person in charge of the project department.
