Stainless Steel Tensile and Proof Stress Of Metric Bolts Screws
Stainless steel include Austenitic, Martensitic and Ferritic..
Austenitic stainless steel..
Chromium nickel steel which can be cold worked. Non magnetic.
Associated grades ( Steel Number according to EN 10088 pt 1) = A1 (1.4305) , A2 (1.4301) ,A3 (1.4541) , A4 (1.4401) and A5 (1.4571).
Martensitic stainless steel ..
Limited corrosion resistance but can be heat treated for superior strength properties. Magnetic Properties.
Associated grades ( Steel Number according to EN 10088 pt 1) = C1 (1.4006 etc) , C3 (1.4057), C4(1.4104)
Ferritic stainless steel..
Plain chromium stainless steel with a chromium content varying between 10.5 and 18% and a low carbon content. They not hardenable by heat treatment. Ferritic alloys have good ductility and formability but a relatively poor high temperature strength compared austenitic grades. Magnetic..
Associated grades = F1
