RAW MATERIAL INFORMATION OF PROTOTYPE STAMPING

H300LAD is a low alloy high-strength hot-dip galvanized carbon steel, coated with pure zinc coating, used for cold forming, standard Q/BQB 420-2003. This is a often used raw material for fast prototype making in vehicle industries like bicycle, motorcyle,autombile etc.

H-high-strength cold formed steel with a lower yield strength limit of 300, L-low alloy, D-hot-dip galvanized, Z-pure zinc, with a normal zinc flower surface structure.

This type of steel is a product of Bao-steel, with a general yield strength of 300-380 and a tensile strength of 380-480. The elongation after fracture is not less than 23%, and the bending center diameter at nominal thickness is 2A, where a is the thickness. Surface treatment usually involves chromate passivation and oil coating to prevent white rust during transportation and storage.
