S355ML material specification need painting or not

SA516 70 grade has the highest tensile and yield strength range due to the highest carbon content (up to 0.28%). For high-grade S355ML material specification steel plates such as SA516 70 grade, especially thick steel plates need to be preheated during arc welding.

Based on the main business of iron and steel, we are committed to producing high-quality, green and efficient steel products. The main steel products are medium and S355ML material specification heavy plate, hot rolled coil, section steel, steel tube, etc., which are widely used in automobile, oil, railway, bridge, construction, electricity, transportation, machinery, shipbuilding and other important fields. Our steel products are exported S355ML material specification to Indonesia, Bangladesh, Myanmar, Iran, Brazil, Mexico, UAE, Iraq, etc Egypt, Mozambique, Ukraine and other dozens of countries and regions.

Blast furnace ironmaking is a traditional ironmaking method based on coke energy. It cooperates with converter steelmaking and is the main method of producing S355ML material specification steel at present. This dominance of blast furnace ironmaking is not expected to change for quite a long time. The essence of blast furnace ironmaking is the reduction of iron. Besides, coke is used as fuel and reducing agent. At high temperatures, iron ore or iron-containing raw materials are reduced from an oxide or mineral state to liquid pig iron.

Weathering steel plates have an excellent corrosive resisting property like resistance to crevice and pitting corrosion, resistance to corrosion and oxidation. This plate also has resistance to chloride corrosion cracking and stress corrosion. These plate are not affected very easily by acids and environmental rust and works in the sulfide atmosphere. S355ML material specification, Weather resistant steel plates have excellent workability, formability, easy to install, easy to fabricated, machinability, durability, reliability.

The 365 day service system is implemented, and the business, loading and delivery are handled as usual in holidays and festivals. Actively help users solve difficulties. When users encounter difficulties in handling business, they should actively coordinate with the external solution; if they need to solve the problems internally, they should solve them in a timely manner without prevarication and wrangling. In line with the S355ML material specification principle of "fairness, justice and timeliness", coordinate with relevant departments and deal with all kinds of objections in a timely manner.
