Description. Stainless-steel-pipe-7Cr17 is a Chinese GB standard Martensitic stainless steel grade produced by adding a small amount of molybdenum (Mo) and vanadium (V) to Stainless-steel-pipe-7Cr17 to improve hardness and wear resistance. Similar international steel grades are US AISI 440A and Japanese SUS 440A.

7Cr17MoV vs 7Cr17. Both 7Cr17MoV and 7Cr17 are low-end, budget stainless steel. They are both Chinese grade and offer a great price to performance value. The biggest difference between the two is that 7Cr17MoV contains Molybdenum and Vanadium elements that increase its wear resistance and hardness.

7Cr17 Steel (68Cr17) High Carbon Stainless Steel. 68Cr17 (7Cr17 Steel) 68Cr17 (7Cr17 steel) is a Chinese high barbon chromium martensitic stainless steel with a higher quenching hardness than 2Cr13 steel. 7Cr17 stainless steel has high strength and hardness under quenching and tempering conditions, and has both stainless and corrosion resistance.
