Automobile steel SPFH540 SPFH590

Baosteel steel SPFH540, SPFH590 of cars for production are mainly used for requirements good forming performance and high strength requirements of automobile frame, wheels, etc, for automotive structural parts

Steel used in the smelting method: steel plate and steel belt for oxygen converter smelting of killed steel. Delivery status: steel plate and steel belt to hot rolled or controlled rolling status of delivery. Surface treatment: the surface of the steel plate and steel belt processing mode can be used on rolling and pickling surface in two ways. Acid pickling surface of steel plate and steel belt, to apply oil or no oil delivery of the goods. After oil pickling of steel plate and steel belt, in the normal packing, transportation, handling and storage conditions, the supplier guarantee from the date of production completion does not produce corrosion, within three months the oil film can eliminate aqueous alkali. As buyer's request to not oiled pickling steel plate and steel belt supplier, should be indicated in the contract. No oil pickling of steel plate and steel belt, corrosion and abrasion in the transport and processing process, the supplier is not guaranteed.
