How to ensure the healthy and stable development of s355jr hot rolled sheet industry

Remove dirt and grease on s355jr hot rolled sheet steel surface before gas cutting, and leave a certain space below to facilitate slag blowing out.When gas cutting, the movement of the cutting torch should be kept at a constant speed, and the cutting surface should be 2-5mm from the tip of the fireworks center.

45# steel is a high-quality carbon structural steel, which is widely used in machinery manufacturing. s355jr hot rolled sheet, 45# steel has good mechanical properties and is relatively cheap. 45# carbon structural steel chemical composition: carbon C: 0.42-0.50, silicon Si: ≤0.40, manganese Mn: 0.50-0.80, sulfur S: ≤0.045, phosphorus P: ≤0.045, chromium Cr: ≤0.40, nickel Ni: ≤0.40, molybdenum Mo: ≤0.10.

The company adheres to the business philosophy of "excellent quality and integrity", aims to create a first-class enterprise in the s355jr hot rolled sheet industry, takes circular economy and resource reuse as the main line, takes energy conservation, emission reduction and sustainable development as the purpose, relies on advanced equipment, perfect transportation infrastructure and good reputation, and strives to become a leading enterprise in the s355jr hot rolled sheet industry with scientific management, high quality, first-class service and harmonious development

From the name, we can clearly know that seamless pipe is seamless steel pipe, which is different from welded pipe. Seamless pipe is actually a kind of steel with hollow section. s355jr hot rolled sheet, Seamless pipe has many advantages, such as: 1, the compressive capacity of seamless pipe is very good, the place with high bearing strength will not crack, and its bearing capacity is very good. 2. Seamless pipe has no welding point, so it is more corrosion-resistant and can bear larger pressure.
