What is special-shaped grade a516 gr 70

Based on the advantages of grade a516 gr 70 steel resources in domestic market and good reputation, combining with the huge international market demand for steel products, our company started the international business in 2010 and successfully being approved and certified by ISO9001:2008, the Registration number is 626014Q11531R0S. With the quality steel grade a516 gr 70 products and professional service, our company was award the international acclaim from infrastructure, shipbuilding, petroleum industry etc., and gradually grow into a bright star in the steel export industry .

16Mo3 material is a pressure vessel and boiler steel grade that is used in applications with elevated temperatures according to EN 10028–2. It has improved mechanical properties and better creep resistance allowing it to be used up to 500°C. 16Mo3 boiler steel is used as a material at elevated operating temperatures, and is used as a weldable steel for manufacturing industrial boilers and stainless steel pressure vessels in the petroleum, natural gas and chemical industries.

12Cr1MoVG high pressure boiler tube belongs to seamless steel tube. The manufacturing method of 12Cr1MoVG high pressure boiler tube is the same as that of seamless steel tube. High pressure boiler tubes are often in high temperature and high pressure conditions when they are used. Under the action of high temperature flue gas and steam, oxidation and corrosion will occur. grade a516 gr 70, 12Cr1MoVG high pressure boiler tube is required to have high endurance strength, high oxidation resistance and corrosion resistance, and good microstructure stability.

Stainless steel plate and other plates are like smelting, refining, casting, rolling, hot rolling and cold rolling is the final process steps in the manufacture of stainless steel. At present most of the world's grade a516 gr 70 stainless steel factory use the AOD furnace furnace ldpe-g-nvp stainless steel production, its production accounted for about 70% of the world's stainless steel output, a VOD furnace a converter three-step method is used to produce stainless steel, its production accounted for about 20% of the world's grade a516 gr 70 stainless steel production, production of stainless steel with other methods, its production accounted for about 10% of the world's production of stainless steel.

What is the difference between Q345B steel and Q345A steel?
grade a516 gr 70, Q345B steel and Q345A steel have slight difference in chemical composition:
Q345A steel: C ≤ 0.20, Mn ≤ 1.7, Si ≤ 0.55, P ≤ 0.045, S ≤ 0.045, V 0.02 ~ 0.15;
Q345B steel: C ≤ 0.20, Mn ≤ 1.7, Si ≤ 0.55, P ≤ 0.040, S ≤ 0.040, V 0.02 ~ 0.15.
The difference between Q345B steel and Q345A steel is mainly in A and B behind the steel grade, Q345A steel grade is not subject to impact; Q345B steel grade needs 20 ℃ room temperature impact test.
