Chemical Composition of Austenitic Chrome Nickel Steels:
The document provides detailed chemical compositions for various austenitic chrome nickel steels according to DIN 17440 standards. Key materials include 303, 304, 304L, S2304, 321, 316, 316L, and 316Ti, with specifications on maximum content for elements like carbon, silicon, manganese, chromium, molybdenum, nickel, and others.

Physical Properties:
Physical properties such as density, modulus of elasticity, thermal expansion, thermal capacity, specific heat capacity, and electrical resistance are provided for materials like X 5 CrNiMo 17 12 2 (1.4401) and X 6 CrNiMoTi 17 12 2 (1.4571).

Mechanical Properties at Room Temperature:
The document outlines mechanical properties including 0.2% and 1% permanent elongation limits, tensile strength, and ductility for materials such as X 5 CrNiMo 17 12 2 (1.4401) and X 6 CrNiMoTi 17 12 2 (1.4571).

Additional Notes:
Schwer-fittings specialize in stainless steel fittings, particularly 1.4571 or AISI 316Ti, and emphasize continuous product development and improvement. The document also notes that small-sized nuts are cold pressed and provides a reference to a works acceptance certificate to DIN 50 049 3.1B.
