430 Stainless steel bar: ferritic stainless steel, decorative, such as for car accessories. Good shape, but heat resistance and corrosion resistance worse. 440 - high strength cutting tool steel, carbon slightly higher, after appropriate heat treatment to obtain a higher yield strength steel profile equipment, hardness up to 58HRC, are among the most hard stainless steel. The most common application example is the "razor blades." There are three common models: 440A, 440B, 440C stainless steel profile processing, in addition to 440F (and easy processing). Lower hardness (≦ 170%) stainless steel profile, internal grain grading between 7.0 to 8.0, excellent deep drawing properties. Many producers thermos pot business class stainless steel profile picture processing of their products generally are higher than (BLANKING SIZE / products in diameter), their processing than 3.0,1.96,2.13,1.98 respectively. SUS304DDQ timber is mainly used for processing these requests higher than that of the product, of course, working ratio of more than 2.0 products are generally subject to few the stretch to complete.
