Is numerical control S275JR carbon steel plate sheet cutting good

The salesman of the company is familiar with all aspects of knowledge. Understand the company profile: group, company profile, various honor certification, enterprise's functional strength and other advantages analysis. Know the main product brand types and specifications of the company, and know the special knowledge of the product (production process and advantages of the product, simple identification method of product quality, etc.)

According to the different manufacturing processes, there are hot rolled steel pipes and cold drawn S275JR carbon steel plate sheet seamless steel pipes. BBN sells seamless pipes of different sizes, weights and grades. Customers can choose between black S275JR carbon steel plate sheet line pipes and galvanized line pipes. From 2-3/8" to 24", steel grade A, B, X42, X80.

Quenching and tempering (QT) is a double heat treatment process of quenching and high temperature tempering. In general, medium carbon steel and medium S275JR carbon steel plate sheet carbon alloy steel often need quenching and tempering treatment. Quenching and tempering can make iron and steel parts obtain a good combination of strength and toughness, with high strength, excellent toughness, plasticity, cutting performance, etc. Some S275JR carbon steel plate sheet alloy steel or low alloy steel must be quenched and tempered to obtain good comprehensive properties. These steels can also be called quenched and tempered steels.

According to GBT3077, 42CrMo steel chemical composition should be within the range (%): 42CrMo carbon content is 0.38-0.45 (C), Silicon content is 0.17-0.37 (Si), Manganese content is 0.50-0.80 (Mn), Chrome content is 0.90-1.20 (Cr), Molybdenum content is 0.15-0.25 (Mo). The high Cr content contrivutes to high strength of 42CrMo steel, with min. yield strength of 930 Mpa, and min. tensile strength of 1080 Mpa. The common heat treatment for S275JR carbon steel plate sheet, 42CrMo steel is quenching and tempering.
