Stainless Steel S41003 Cold Drawn vs S41003 Q&T 600

Stainless Steel · S41003 temper comparison

S41003 Cold Drawn and S41003 Q&T 600 are two conditions of the same stainless steel grade, S41003: Cold Drawn versus Q&T 600 (Q&T). The chemistry is identical, so every difference below comes from the condition. S41003 Q&T 600 is the stronger of the two: yield strength 550 MPa (79.8 ksi) against 520 MPa (75.4 ksi) for S41003 Cold Drawn, about 6% more; tensile strength follows at 700 MPa (102 ksi) vs 640 MPa (92.8 ksi). S41003 Q&T 600 is the more ductile: elongation 18% versus 15% for S41003 Cold Drawn, and S41003 Q&T 600 is harder (230 HB vs 210 HB). On the shop floor, S41003 Cold Drawn machines more easily (good vs fair).
