S690QL brinell hr hot rolled plate heavy plate

Based on the advantages of S690QL brinell steel resources in domestic market and good reputation, combining with the huge international market demand for steel products, our company started the international business in 2010 and successfully being approved and certified by ISO9001:2008, the Registration number is 626014Q11531R0S. With the quality steel S690QL brinell products and professional service, our company was award the international acclaim from infrastructure, shipbuilding, petroleum industry etc., and gradually grow into a bright star in the steel export industry .

10CrMo9-10 steel plate is a kind of European standard pressure vessel steel plate, which is heat-resistant and high-pressure resistant boiler steel plate, belonging to alloy pressure vessel steel plate; 10CrMo9-10 steel plate is mainly used for power station boiler drum and steam boiler equipment. The S690QL brinell delivery state of 10CrMo9-10 steel plate is usually normalizing + tempering.

Sprin steel refers to the special alloy steel used to manufacture all kinds of springs and other elastic elements. S690QL brinell, Spring steel has excellent comprehensive performance, good surface quality, accurate shape and size. The smelting of S690QL brinell, spring steel is very important. It is necessary to ensure excellent metallurgical quality, not only to ensure accurate chemical composition, but also to guarantee high purity. The content of sulfur, phosphorus, oxygen and nitrogen of spring steel should be low, and the uniformity and stability of spring steel should be good.

As the thickness and hardness of S690QL brinell increase, the tendency to crack at the cutting edge increases. In order to prevent the S690QL brinell from cutting cracks, preheating should be carried out before S690QL brinell cutting. Special attention should be paid to preheating to make the entire S690QL brinell interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole S690QL brinell cannot be preheated, the partial preheating method can be used instead.

The difference between S690QL brinell, 10# seamless steel pipe and 20# seamless steel pipe:
1. Chemical composition
Chemical composition of 10# seamless steel pipe: C: 0.07-0.13, Si: 0.17-0.37, Mn: 0.35-0.65, Cr: 0.15, Ni: 0.30, Cu: 0.25. Chemical composition of 20# seamless steel pipe: C: 0.07-0.23, Si: 0.17-0.37, Mn: 0.35-0.65, Cr: 0.25, Ni: 0.30, Cu: 0.25
2. Mechanical properties
10# seamless steel pipe: tensile strength: 335 MPa, yield strength: 205 MPa, elongation: 31%. 20# seamless steel pipe: tensile strength: 410 MPa, yield strength: 245 MPa, elongation: 25%.
