As the name implies, automobile steel plate is a special steel plate material used in automobile manufacturing. With the increasing quality of people's lives nowadays, the demand for automobiles is also increasing, making the automobile manufacturing and sales industries very hot in recent years. Automobile steel plates are undoubtedly one of the important materials for automobile construction, and the quality requirements for SPA-C material, automobile steel plates in automobile manufacturing are also very high. The quality of automotive steel plates is directly related to the quality and safety of automotive products and pricing.

We are one of the largest weathering steel stock keepers in China and even in the world. For most specs weathering steel materials, we can arrange delivery within 5 days. Meanwhile, our weathering steel price is competitive. And for weathering steel coils, we do slit, SPA-C material plate cut and so on further processing. We can meet different size and shape needs of customers.

The strengthening mechanisms in metals mainly include solid solution strengthening, dislocation strengthening, fine grain strengthening, and second phase (precipitation and dispersion) strengthening. Alloying elements have the most significant strengthening effect on steel in the quenched and tempered state, because it makes full use of all four strengthening mechanisms. Martensite is formed during quenching, and carbides are precipitated during tempering, resulting in a strong second phase strengthening and greatly improving toughness. Therefore, obtaining martensite and tempering it is the most economical and effective comprehensive strengthening method for SPA-C material.
