Some steel grade S355ML, low-alloy high-strength steels have good atmospheric corrosion resistance. In some cases, appropriate precautions can be taken, and they can even be used without being coated in the atmosphere. The elements that improve atmospheric corrosion resistance are copper, phosphorus, silicon, chromium, nickel and molybdenum. The excellent atmospheric corrosion resistance of some low-alloy high-strength steels has led to the formation of new concepts in the design of buildings, bridges and other structures, that is, these structures are constructed with appropriate exposed components of low-alloy high-strength steel.

First to determine the welding methods, such as hand arc welding, submerged arc welding and tungsten argon arc welding, melting polar gas shielded welding machine, and so on are very many different kinds of steel grade S355ML welding method, can only be chosen according to specific situation, determine the welding method, and make welding process parameters, different kinds of welding process parameters, such as manual welding mainly includes: electrode model (or brand) diameter, current, voltage, welding power source type and polarity connection, welding layer number, number, inspection method, etc.

As to the Chemical composition, the different content is a main on carbon content, while the carbon content of steel grade S355ML, A283Gr. D is no more than 0.27% and it is higher than Grade C (≤0.24%) ; as to the mechanical property, the differences are tensile strength and yield strength, while the tensile strength of ASTM A283 Gr.D is 415-550MPa (60-80 ksi) and yield strength of ASTM A283 Grade D is 230MPa (33 ksi).

Facing the new situation and facing new goals, the company revolves around the sixteen-character development policy of “prioritizing production preservation, society-oriented, market operation, and brand creation and efficiency”. Layout the country in accordance with the modern logistics model, and accelerate the establishment of a modern integrated steel enterprise integrating steel storage, transportation, processing, and distribution.

We are engaged in steel grade S355ML corten steel, weathering steel, atmosphere corrosion resistant steel materials. After receiving your inquiry about the weathering steel, we will make quotation for you at the first time. Meanwhile, our professional team can give you valuable answers about all kinds of question about the weathering steel. For example, corten steel cost per square foot, S355J2WP equivalent, steel grade S355ML ASTM A242 steel properties, A588 steel yield strength, etc. If you have any demands or questions about weathering steel, please feel free to contact us.
