Principle of surface pretreatment of RINA grade E wash bulkhead steel

In production and operation, the company always attaches great importance to product RINA grade E wash bulkhead steel quality. Product quality is stable, performance index is superior, after-sales service is in place, the company's products have been exported to the United States, Southeast Asia, Africa, the Middle East and other countries and regions, occupying a large part of the overseas market RINA grade E wash bulkhead steel. And a large number of famous enterprises at home and abroad have formed a solid strategic partnership with the company.

RINA grade E wash bulkhead steel, A335 P22 is a steel grade of American Standard boiler tube, and the executive standard is ASTM A335 / A335M, which is chromium molybdenum high temperature ferritic steel for boiler and superheater. A335P22 alloy pipe is mainly used as heating surface pipe of low and medium pressure boiler (working pressure is generally not more than 5.88 MPA, working temperature is below 450℃); A335P22 alloy pipe is also used as economizer, superheater, reheater and petrochemical industry pipe of high pressure boiler (working pressure is generally above 9.8MPa and working temperature is between 450℃ and 650℃).

Stainless steel plate is a general term for stainless steel plate and acid-resistant steel plate, and is a steel plate with good corrosion resistance and rust resistance on the surface. The surface of RINA grade E wash bulkhead steel, stainless steel plate is very smooth and clean. It has high toughness, plasticity, and is not easy to be corroded and rusted. Stainless steel plate has corrosion resistance and high temperature oxidation resistance. Stainless steel is durable, can be stored outdoors for a long time, and will not be damaged in bad weather. Stainless steel plate is not easy to rust, but it is not absolutely not rusty.

RINA grade E wash bulkhead steel, Wear-resistant steel plates are composed of two parts, namely carbon steel plate and alloy wear-resistant layer. Under normal circumstances, the thickness of the alloy wear-resistant layer of the wear-resistant steel plate is 1/3-1/2 of the total thickness. When working, the matrix provides comprehensive properties such as strength, toughness and plasticity against external forces. And the alloy wear-resistant layer provides wear-resistant properties to meet the requirements of specified working conditions.
