What is the difference between SPA-C atmospheric corrosion resistant steel plate & A36?

We are a professional SPA-C atmospheric corrosion resistant steel plate steel raw material supplier with a history of 17 years. After years of development, the company's steel plates and coils are widely used in construction, machinery manufacturing, container manufacturing, shipbuilding, bridge construction and other fields around the world. With good product SPA-C atmospheric corrosion resistant steel plate quality, we have solid project cooperation with foreign governments or leading enterprises such as Egypt, Bangladesh, Myanmar, Thailand, Philippines, Vietnam, Venezuela, Peru, Mexico, the United States, Portugal, Russia, Iran, Iraq, Pakistan, etc.

For SPA-C atmospheric corrosion resistant steel plate ASTM A106 seamless steel pipe could transport fluids or gasses at high temperature and pressure levels, with 3 grades A, B, C, most common used ASTM A106 Grade B SPA-C atmospheric corrosion resistant steel plate is widely used in the projects of oil and gas refineries, power plants, petrochemical plants, boilers.

Our SA516Gr70 pressure vessel plate has good impact resistance, small temperature deformation, good welding performance, good fatigue resistance, good anti-layered cracking performance, micro-alloying, high purity, low carbon equivalent, strong resistance to sulfur and hydrogen. The product has good dimensional tolerance and surface quality. China made SPA-C atmospheric corrosion resistant steel plate steel plates are now widely used in major chemical sites.

Vanadium is a weak deoxidizer. Adding vanadium into SPA-C atmospheric corrosion resistant steel plate steel can reduce the adverse effects of carbon and nitrogen, effectively improve the strength, but sometimes also increase the tendency of welding hardening, vanadium is also a commonly used trace alloy element.

A131 EH36 steel is high strength marine grade hull structural steel. Its yield strength is no less than 355Mpa, tensile strength is 490-620 Mpa, and elongation is 19% min. SPA-C atmospheric corrosion resistant steel plate, EH36 steel strength is close to S355 steel. However, EH36 steel is shipbuilding steel, while S355 steel is carbon structural steel, and can not be certified by classification society. That is to say, S355 steel is not allowed to be used for ship building when there is certificate requirement. A131 EH36 steel is widely used to build ships working in low temperature water.

Hot rolled plates are known for their superior mechanical properties over commodity grades of merchant bar. The hot rolled SPA-C atmospheric corrosion resistant steel plate plates products are made to specific chemistry and mechanical properties ranges, allowing them to be used in engineered applications. Resulting shafts, axles, and gears can be used in the automotive SPA-C atmospheric corrosion resistant steel plate industry and agriculture equipment. A36 mild steel has good strength, formability, and excellent welding properties. We also can supply welding, fabricating, and bending service.

Our company has established and constantly improved the customer service system and emergency response system. Through the customer service management system, we track the service of the after-sales service team and provide efficient and standard services in time. At the same time, the company formulates a regular return visit system, compares the historical cases of customer problems, proposes a pre solution, and ensures that the service is in place in a short time.
