EN 10025 S420ML steel supplier equivalent grades

EN 10025 S420ML steel supplier, A335 P22 is a steel grade of American Standard boiler tube, and the executive standard is ASTM A335 / A335M, which is chromium molybdenum high temperature ferritic steel for boiler and superheater. A335P22 alloy pipe is mainly used as heating surface pipe of low and medium pressure boiler (working pressure is generally not more than 5.88 MPA, working temperature is below 450℃); A335P22 alloy pipe is also used as economizer, superheater, reheater and petrochemical industry pipe of high pressure boiler (working pressure is generally above 9.8MPa and working temperature is between 450℃ and 650℃).

The company adheres to the business philosophy of "excellent quality and integrity", aims to create a first-class enterprise in the EN 10025 S420ML steel supplier 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 EN 10025 S420ML steel supplier industry with scientific management, high quality, first-class service and harmonious development

In order to easily and economically perform hot or cold processing to make various parts of engineering structures, the low alloy high strength steel must have appropriate forming properties. Like EN 10025 S420ML steel supplier, carbon structural steel, low alloy high strength steel can generally be processed in such way, as well as cutting, punching, and machining. Although the yield point of low alloy high strength steel is high, even if the forming operation is deformed quite severely, cold bending presses, drawing machines, presses and other equipment used for carbon structural steel forming can also be used for low alloy high strength steel, but some equipment needs to be modified.

With the increase of temperature, the yield limit of EN 10025 S420ML steel supplier will decrease monotonically, but the tensile strength of EN 10025 S420ML steel supplier will rise to a high peak value at a certain temperature, and then decrease. This peak temperature is called the blue brittleness temperature of EN 10025 S420ML steel supplier. Near the blue brittleness temperature, the EN 10025 S420ML steel supplier strength increases and the plasticity decreases. The elongation and section shrinkage of EN 10025 S420ML steel supplier increase with the increase of temperature, but there is a low peak at the blue brittleness temperature. The blue brittleness temperature of low carbon steel ranges from 200 ℃ to 250 ℃. The blue brittleness of low alloy steel is not obvious as that of low carbon steel, and the blue brittleness temperature is higher.

As one of the large professional metallurgical manufacturers in China, the strength of the brand, quality assurance, professional after-sales. Every day we are making unremitting efforts to challenge higher quality EN 10025 S420ML steel supplier products and more satisfactory services. Customer demand is our pursuit, and win customer satisfaction with quality. BBN after-sales team is responsible to solve the problem of technical support and quality, service complaints.
