45# seamless steel pipe (No.45 seamless steel pipe) is Chinese high-quality carbon structural steel, which is called S45C in Japanese standard, AISI 1045 in American standard, and C45 in German standard. The difference between 45# seamless steel pipe and 20# seamless steel pipe is that its hardness is obviously higher than that of 20# seamless steel pipe. The tempering brittleness of S355M steel, 45# seamless steel pipe is high. After quenching and tempering, 45# seamless steel pipe has good mechanical properties. If the wear resistance is considered, heat treatment is required.

Corrosion resistant steel is a kind of stainless steel, which can resist corrosion in some strong corrosive media. Stainless steel can only resist corrosion in air or weak medium. Stainless steel is not necessarily corrosion resistant, corrosion-resistant steel must be stainless steel. Corrosion resistant steel is durable and can be stored outdoors for a long time without being damaged in bad weather. Corrosion resistant steel is not easy to rust, but it is not absolutely rust free. The strength, precision and toughness of S355M steel, corrosion resistant steel are very good, and can be the processed and used for many purposes.

The hot rolling method is to heat the S355M steel steel material to about 1000 ℃ ~ 1250 ℃ and use the rolling mill to roll it. The traditional hot rolling process is generally divided into the following two steps: the first step is to use the primary rolling mill or billet rolling mill to roll the ingot, billet or continuous casting billet into a certain shape and size of billet. This kind of S355M steel rolling process is usually called semi-finished product production, also called blank production.

The high strength S355M steel low alloy steel, which is shorten as HSLA steel, is one of our main products. We have professional team to serve you. For any demands or questions about HSLA steel, for example, ASTM A572 grade 50 chemical composition, difference between S355JR and S355J2, mechanical properties of S355M steel ST52 steel, Q345B tensile strength, Q345D steel ASTM equivalent, HSLA steel price etc. , please do not hesitate to contact us and consult.

The 2019 Year of the Pig is the 70th anniversary of the founding of the People's Republic of China. Growing up with the motherland, our company sang songs to the mark the 70th victory anniversary. In September, we organized all employees to sing "My Country and I" and made a film.
