Effect of humidity and temperature on corrosion of Q460D carbon steel plate sheet

Our company was founded in 2000, which initially committed to providing high-quality steel Q460D carbon steel plate sheet products for China's rapid infrastructure construction. With the advantages of steel resources and good reputation in the domestic market, combined with the huge demand for steel in the international market, we began to export Q460D carbon steel plate sheet steel to the international market, opening up the international steel market.

14Cr1MoR pressure vessel steel belongs to Cr-Mo anti-hydrogen steel.It is suitable for large-scale equipment such as petrochemical, nuclear power, steam turbine cylinders, thermal power and other high temperature and high pressure, and hydrogen or hydrogen mixed medium. These Q460D carbon steel plate sheet products are also suitable for large equipment such as petrochemical, nuclear power, steam turbine cylinder, thermal power and other high temperature and high pressure, and hydrogen or hydrogen mixed medium.

Weathering steel plate refers to the low alloy structural steel with protective rust layer and atmospheric corrosion resistance, which can be used to manufacture steel structures such as vehicles, bridges, towers, containers, etc. Compared with Q460D carbon steel plate sheet, ordinary carbon steel, weathering steel has better corrosion resistance in the atmosphere. Compared with stainless steel, weathering steel has only a small amount of alloy elements, such as phosphorus, copper, chromium, nickel, molybdenum, niobium, vanadium, titanium and so on. The total amount of alloy elements only accounts for a few percent, instead of more than 10 percent as stainless steel, so the weathering steel price is relatively low.

Heat treatment process: heat treatment refers to a kind of process operation in which the metal or alloy can change the internal structure through certain heating, heat preservation and cooling methods in the solid range to obtain the required performance. Q460D carbon steel plate sheet Heat treatment process refers to the ability to change the microstructure and properties of Q460D carbon steel plate sheet after heat treatment, including hardenability, hardenability, temper brittleness, etc.

StE 480.7 TM steel plate/pipes,under DIN 17172 standard, we can regard StE 480.7 TM steel plate/pipes as large diameter pipes. Q460D carbon steel plate sheet, StE 480.7 TM steel plate/pipes is one mainly of Steel for large diameter pipes,DIN 17172 StE 480.7 TM steel with the demands in mechanical properties of the pipes followed the DIN 17172 specification for grade StE 480.7 TM(YS is 485MPa, TS is from 600-750 MPa).It is well known that a low carbon bainitic microstructure offers an excellent combination of strength and toughness.

Our company will accept the product quality objection registration record, pass it to the Q460D carbon steel plate sheet production unit and relevant departments, and timely coordinate the supervision of product Q460D carbon steel plate sheet quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
