416 stainless steel rod
416 stainless steel is a steel with better cutting performance in stainless steel. 416 stainless steel is mainly used in the production of solenoid valves, micro-motors and electrical components. The above materials are all free-cutting stainless steel, especially suitable for mass production of automatic lathes and CNC lathes.
416 stainless steel bar standard: AISI, ASTM Model: 416 UNS number: S41600
Introduction
Name: Martensitic stainless steel
Standard: AISI, ASTM
Model Number: 416
UNS number: S41600
Chinese brand: Y1Cr13
416 stainless steel rod Characteristic
416 stainless steel has low carbon content and good corrosion resistance. 416 is a free-cutting martensitic stainless steel. It can be strengthened by heat treatment. The strength and machinability of 416 is better than that of 304 and 316. The friction coefficient is small, but the corrosion resistance is not as good as 304 and 316.

416 stainless steel rod Heat treatment range
Since the tissue structure is a body-centered cubic structure, the strength drops sharply at high temperatures. Below 600 ° C, the high temperature strength is the highest among all types of stainless steel, and the creep strength is also the highest.
Heat treatment specifications: 1) Annealing, 800-900 ° C slow cooling or about 750 ° C rapid cooling; 2) quenching, 920 ~ 980 ° C oil cooling; 3) tempering, 600 ~ 750 ° C rapid cooling.
Metallographic organization: The tissue is characterized by martensite type.
Delivery status: generally delivered in heat treatment state
