This hex nut is manufactured to DIN 934 standards and features metric threading. It's made from duplex stainless steel 1.4462 (D6), a material that offers strong resistance to both pitting and intergranular corrosion. Duplex stainless steel 1.4462 brings together the best of austenitic and ferritic stainless steels, pairing the higher tensile strength of ferritic chromium steel with the corrosion resistance of austenitic chromium-nickel steel.
