What material can be used to produce high strength 12.9 stainless steel screws round head? Can material 10B21 be used?

Mr. Gao from Guangzhou wants to order 3,000 pieces of high-strength 12.9-grade stainless steel screws round head. He used the material of 10B21 before but found that the strength of the screws did not meet his requirements after use. This time, Mr. Gao would like to consult the reason for the screws’ customization of Shi Shi Tong.

Manager Liu, who manages the production of the factory, told him that although 10B21 also belongs to alloy steel, the strength grade and performance grade of the screws produced with it cannot meet the 12.9 grade after hardening. Finally, the engineering department suggested Mr. Gao use SCM435 material to produce screws because its strength could fully meet his requirements after heat treatment and electroplating to remove hydrogen.

If you are looking for high strength 12.9-grade stainless steel screws round head or other types of screws, you can contact Shi Shi Tong stainless steel screw supplier.
