What kind of electrode is used to weld S420M steel

The shipping department of the company arranges shipping booking for customers' goods in advance, and makes good matching with inland transportation. Effectively manage and follow up the customer's shipping schedule and give feedback to customers in time. At the same time, the shipping department has a keen insight into the shipping market in different periods to reduce the transportation cost for the company and customers.

At present, S420M steel abrasion resistant steel plate thickness is between 8-100mm, the hardness of up to 500HBW. Thin steel sheet and ultra-wide steel plate has been developed for special use.

ASTM A285 grade A standard specification for pressure vessel plates. S420M steel, carbon steel, low- and intermediate-tensile strength. ASTM A285 grade A plates are normally supplied in the as-rolled condition. The plates may be ordered normalized or stress relieved, or both.Supplementary Technology: HIC Test I NACE MR0175 1 215 | Z25 | 235 | S57 | S57.1| S58 | S58.1 1S3 |S4 Thickness: 6MM to 300MM.Width: 1500mm to 4050mm.

Main characteristics of 12Cr1MoV Steel: compared with 12CrMoV steel, 12Cr1MoV steel has higher oxidation resistance and thermal strength. The creep limit of 12Cr1MoV steel is very close to the endurance strength value, and it has high plasticity under the condition of endurance tension; the processability and weldability of 12Cr1MoV steel are good, but it needs to be preheated to 300 ℃ before welding, and stress removal treatment after welding. 12Cr1MoV steel is widely used in Superheater, header and main steam pipe of high pressure, ultra-high pressure and subcritical utility boiler.

Through the operation and management, brand advantage and improve pre-sales, sale of after-sales service, the efforts of the company into the industry leading enterprises.Relying on perfect quality management system, it has built up competition predominance and provided high quality, favorable price and perfect after service for customers.
