Grade 12.9 screws and titanium alloy screws are stronger

High strength grade 12.9 screws.

Look at the use of the environment, in corrosive environment, stainless steel screw oxidation resistance, corrosion resistance, stainless steel screw good point.

In high-strength, high-impact environments, class 12.9 is the top variety of screws with high hardness and tensile strength, with rockwell hardness (HRC) ranging from 39 to 44 and tensile strength up to 1220N/mm2.

Ferritic stainless steel. Chromium 12% ~ 30%. The corrosion resistance, toughness and SOLderability of DU are improved with the increase of chromium content, and the chloride stress corrosion resistance of DU is better than other stainless steels. It can be divided into Cr system (SUS400), Cr-Ni system (SUS300), Cr-Mn-Ni system (SUS200) and precipitate hardening system (SUS600).

So stainless steel screws don't have that much strength. If the use of the environment and conditions do not require such a high strength, still can use 8.8 stainless steel screws.
