Cause analysis of red oxide iron on nuance SMA400AW surface

nuance SMA400AW, Pressure vessel steel plate is mainly used to make pressure vessels. But according to its temperature, corrosion resistance and other characteristics, the material of the pressure vessel steel plate used for pressure vessels is also different. The most common oil tanks in our lives, liquefied gas tanks are all made of pressure vessel steel plates. According to the purpose, the pressure vessel steel plate can generally be divided into: pressure vessel steel plate, low temperature pressure vessel steel plate and boiler pressure vessel steel plate, etc..

The wear-resistant layer of nuance SMA400AW wear-resistant steel plate is mainly composed of chromium alloy, and other alloy components such as manganese, molybdenum, niobium and nickel are added. The carbide in the microstructure is distributed in the form of fiber, and the direction of the fiber is perpendicular to the surface. The microhardness of carbides can reach hv1700-2000 and HRC58-62 respectively. The alloy nuance SMA400AW carbide has strong stability at high temperature, high hardness and good oxidation resistance. It can be used normally within 500 ℃.

TMCP process is an important means to improve the comprehensive properties of steel. It can be used to produce ship plate, vessel plate, boiler plate, bridge steel, etc. Compared with the normalized steel of the same strength grade, TMCP can reduce the alloy content of the nuance SMA400AW steel, reduce the carbon equivalent and improve the welding performance. TMCP is more and more widely used in various types of steel rolling industry.

There is a silo technology R&D center in our company with many experts. Our technical backbones go abroad to study advanced technologies regularly to make our technology and products leading in the world. We provide our customers with nuance SMA400AW high-quality steel plates, the excellent quality from specialty. With good reputation, high-quality products, strong strength, and low prices, we welcome the clients from the world to come to visit our factory.

We have a professional after-sales department to collect all information related to customers, so as to make relevant treatment in time according to the information, and file it; guide the user's product use methods and precautions; coordinate with the sales department, visit customers regularly, understand the customer's use and new requirements, and make a customer visit record; When communicating with customers, they should be enthusiastic and careful to understand the situation of product problems and put forward solutions
