Specifies technical delivery conditions for construction stainless steel sheet/plate and strip. Applies to standard and special grades with corrosion resistance up to 1.2% Cr. Does not cover products processed with altered quality characteristics
Intergranular corrosion occurs when material's grain boundaries are more susceptible than their insides. Grain boundary depletion occurs when corrosion-inhibiting elements like chromium are depleted. Chromium carbide precipitation forms at grain boundaries in stainless steels
17-4PH is a precipitation hardened martensitic stainless steel containing copper and niobium/tantalum. Features high strength, hardness and corrosion resistance up to 320°C. Compression strength reaches 1100-1300mpa (160-190ksi) through heat treatment. Contains 15-17.5% chromium for superior corrosion resistance
Duplex stainless steel combines ferritic and austenitic properties. Modified from S31803 grade, endorsed in 1996. Offers higher corrosion resistance than grade 316. Not suitable for temperatures below -50°C
Austenitic chromium-nickel stainless steel with PREN value 17.5-21.1. Tensile strength ranges from 500 to 700 N/mm². Non-magnetic with low magnetisability. Density of 7.9 kg/dm³ at 20°C
Metric DIN 125 flat washers are circular metal discs with central holes. Used to distribute load over larger bearing surface below bolt head. Available in sizes M3 to M72 in various materials including aluminum, brass, nylon
