Effect of humidity and temperature on corrosion of CCS FH40 hull frame steel

ASTM A537 steel is a heat-treated carbon silicon manganese steel plate for ASTM pressure vessels, which is divided into 3 levels A537 CL1, A537 CL2, A537 CL3. CCS FH40 hull frame steel, A537 CL1 plates delivery status: normalizing; When the A537 CL1 plate thickness is ≤65mm, the yield strength is ≥345MPa, and the tensile strength is ≥485MPa. When the thickness is 65 - 100mm, the yield strength is ≥310MPa and the tensile strength is ≥450MPa.

The company produces seamless steel pipes such as GB, ASTM, etc. all year round, including low and medium pressure boiler steel pipes, high pressure boiler steel pipes, CCS FH40 hull frame steel seamless steel pipes for ships and petroleum cracking CCS FH40 hull frame steel steel pipes, Seamless steel pipe, oil sleeve steel pipe, pipeline steel pipe, hollow sucker rod, common fluid steel pipe, structural pipe, kauden steel pipe, seawater corrosion-resistant titanium pipe and imported alloy steel pipe are used for high-pressure fertilizer equipment. The products are widely used in petroleum, chemical, electric, boiler, ship, machinery and other industries, and have been sold all over the country. Many CCS FH40 hull frame steel products have been exported to the Middle East, India, Southeast Asia and Europe and America.

Steel plate cutting and machining parts are mainly used in machinery manufacturing, ships building, landscape building, petroleum storage tanks, steel structures and mold processing industries. We can provide finished and semi-finished CCS FH40 hull frame steel steel plates products according to the client needs. Realize the service from product drawings-steel plate procurement-steel plate cutting-steel plate processing CCS FH40 hull frame steel steel plate distribution services, so as to save customers manpower and material resources.

When the steel plate containing molybdenum only is at high temperature for a long time, the carbon will aggregate into graphite and precipitate, which will worsen the performance. To eliminate this tendency, chromium is often added to the CCS FH40 hull frame steel, steel plate at the same time. When chromium is added to the steel plate, the heat strength, high temperature oxidation resistance and corrosion resistance can also be improved.

First of all, we should establish a correct concept of after-sales service. Service concept is an important part of corporate culture and a long-term enterprise value concept. Our company's after-sales service embodies the concept of "customer first, sincere service for customers". As long as we are in the "sincere service for users" under the guidance of the idea, I believe we will get rich returns.
