Anti-corrosion screws made of special alloy steel MAT21 (ASTM/UNS N06210)

Suitable for Semiconductor devices & chemical plants

NBK released a new socket head cap screw “SNSMT” series that is made of alloy steel ASTM UNS N06210 (MAT21*).

MAT21 is a nickel-chromium-molybdenum-tantalum alloy with improved corrosion resistance. It is a much-awaited, unprecedented alloy that is better than stainless steel, even better than the other Ni-Cr-Mo corrosion-resistant alloys which are known for their high corrosion resistance under various conditions.

MAT21 demonstrates excellent corrosion resistance in both oxidizing and reducing environments.

In a wide range of corrosive environments, it demonstrates better corrosion resistance than Hastelloy * C-22 and C-276.

The screws come with cleanroom wash/cleanroom packing as standard, for your convenience.

Suitable Applications:

FPD production equipment / Semiconductor devices / Printed circuit board etching devices /

Metallic surface treatment equipment and facilities / Chemical plants

Size: M3 - M8
