The sa573 grade 70 structural steel carbon plate is a highly cost effective alternative

15Mo3 steel is a kind of pearlitic heat-resistant steel, which can still show its characteristics under high temperature and long time load. 15Mo3 steel is used for heating surface of sa573 grade 70 structural steel carbon plate low and medium pressure boiler (working pressure is generally not more than 5.88MPA, and working temperature is below 450 ℃). 15Mo3 steel is widely used in petroleum, chemical industry, power station, boiler and other industries. 15Mo3 steel is used to make reactor, heat exchanger, separator, spherical tank, oil and gas tank, liquefied gas tank, etc.

When phosphorus, copper, chromium, nickel and other trace elements are added to the steel, sa573 grade 70 structural steel carbon plate, a dense and strong adhesive protective film will be formed on the steel surface, which will prevent the corrosion from spreading and developing inward, and protect the substrate under the rust layer, so as to slow down the corrosion rate. The amorphous spinel oxide layer of about 50 μ m ~ 100 μ m thickness formed between the rust layer and the substrate is compact and has good adhesion with the substrate metal.

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. sa573 grade 70 structural steel carbon plate Heat treatment process refers to the ability to change the microstructure and properties of sa573 grade 70 structural steel carbon plate after heat treatment, including hardenability, hardenability, temper brittleness, etc.
