Welding S420ML hardness steel heat treatment

Our company attaches great importance to technical support and after-sales service, and has established a customer service center to provide unified technical support and service for S420ML hardness various engineering projects. Customer service center has a strong technical force of technical service team, composed of a customer service center manager, several S420ML hardness after-sales service personnel, responsible for unified acceptance and processing of local after-sales service needs.

The service temperature of high pressure seamless steel pipe is below 450 ℃, and the domestic pipes are mainly made of S420ML hardness, No.10 and No.20 carbon steel hot-rolled pipes or cold drawn pipes. High pressure seamless steel pipe is often used in high temperature and high pressure conditions. Under the action of high temperature flue gas and water vapor, the pipe will be oxidized and corroded. The steel pipe is required to have high endurance strength, high oxidation resistance and corrosion resistance, and good structure stability.

"High strength low alloy steel plate pecifications: S420ML hardness, A516 Grade 60 plates and sheets are producted with thickness up to 200mm [8 inch].A516 Grade 60/70 Dual Certified HIC NACE TM0284 Plates Hydrogen Induced Cracking;Hot Rolled Steel ASTM A516 Grade 60 Dual Certified HIC Tested Plates in accordance with Nace Test Method, ASTM A516 70 HIC Tested (Hydrogen Induced);Tested Fine Grained Pressure Vessel Steel Plates For Sour Gas Service."

The company selects steel raw materials and controls every quality link from the source to ensure high quality. Each process is strictly checked to ensure that there is zero failure rate in the customer's on-site use. Provide customers with high-quality S420ML hardness products and services with an innovative spirit and work together with customers to create a better future. The company can process and cut various special-shaped parts according to customer needs, and can also customize futures of various material specifications according to requirements.

After-sales service team is a key department to test the steel quality. Product quality is always the foundation of our survival and development. The company's full inspection from raw materials to finished products; and implements standardized, scientific, and strict internal quality control and management systems in accordance with the process flow during the production process; products can only leave the factory if qualified, and follow-up problem solving systems are implemented in after-sales services to guarantee the customers’ interest.

Company through its own S420ML hardness website, multimedia, radio, newspapers, the group, the handbook of the corporate culture carrier, approved and publicity column, in-depth to carry out enterprise culture construction, also through photography, painting, calligraphy, cartoon, speech, and the songs of the enterprise design, various cultural and sports activities to carry out enterprise culture construction.
