Product Q&A
Q:Are you a manufacturer or trading company?
A:
We are a direct manufacturer - 2,000 sqm, 17 years of experience, 30+ CNC machines and precision grinding equipment, ISO9001, 3D CMM.
Q:What is 416 stainless steel?
A:
416 (UNS S41600) is a free-machining martensitic stainless steel with 12-14% chromium and sulfur added to enhance machinability. It was the first free-machining stainless steel ever developed.
Q:What is the machinability of 416?
A:
416 has the highest machinability of any stainless steel at approximately 85% of free-machining carbon steel.
Q:What precision grinding tolerances can you achieve?
A:
We achieve +/-0.002mm on critical diameters and features, with surface roughness down to Ra <= 0.2um.
Q:Can 416 be heat treated?
A:
Yes. 416 can be hardened by heat treatment to higher strength and hardness levels. Condition T (HRC 26-32) represents the optimum condition for both machinability and corrosion resistance.
