热轧酸洗钢SPHC SPHD SPHE SPHF

SPHC这个牌号其实最早是德国的牌号，日本也用，后来国内钢厂宝钢引入，代表的是的热轧钢板（它对应的冷轧板就是SPCC），相当于国标GB699（优质碳素结构钢国家标准）中的10#、15#钢的热轧板，他们的含碳量范围是0.1-0.15%左右。

SPHC跟Q235之类的不可相互转换，因为Q235遵循的是国标GB700（碳素结构钢国家标准）的标准，如果仅仅从含碳量上来讲，SPHC跟Q215是一样的，按产品类别分为： 热轧钢带 热轧钢板  热轧纵切钢带 热轧酸洗钢带 热轧酸洗钢板。SPHC，Q195，SAE1006，08YU，含碳量均为6个左右属于冷成型用钢，适用于制造冷型加工的零件。一般用于如冷轧产品，加工有一定延伸要求的冲压成型产品，复杂形状的零件加工。以上几种牌号化学成份及机械性能基本接近，但各钢厂生产的材料在开增加工时，板面平整度会有定区别。

Hot-rolled pickling steel SPHC SPHD SPHE SPHF

SPHC this brand is actually the earliest German brand, also used in Japan, domestic steel mill of baosteel is introduced later, yes for hot rolled steel plate (its corresponding manufacture (SPCC)), equivalent to gb GB699 (national standard for high quality carbon structural steel) in the 10 # and 15 # steel hot rolled plate, their carbon content range is 0.1-0.15%.

SPHC with Q235 is mutual conversion, such as Q235 follows the GB700 gb (national standard for carbon structural steel) standards, if only for carbon content, the SPHC is the same with Q215, according to the product category is divided into: hot rolled steel belt slitting and hot rolled steel plate hot rolled steel strip hot-rolled pickling steel pickling steel plate. SPHC, Q195, SAE1006, 08 yu, carbon content are around six belongs to cold forming steel, is suitable for manufacturing cold type processing parts. Commonly used in such as cold rolled products, has certain extending requirements stamping molding products processing, complex shape parts processing. Above several brands of chemical composition and mechanical properties of the basic approach, but the steel production of materials in the increased working hours and surface roughness will be difference.
