What is the material of 4 16 and what brand does it correspond to in China?

4 16 is a kind of stainless steel with good machinability, and its domestic brand is Y 1Cr 13.

Martensite stainless steel, standard: AISI, ASTM, model: 4 16, UNS number: S4 1600.

4 16 stainless steel is mainly used to produce solenoid valves, micromotors and electrical components. All the above materials are free-cutting stainless steel, which is especially suitable for mass production of automatic lathes and CNC lathes.

Extended data

Features:

4 16 stainless steel has low carbon content and good corrosion resistance. 4 16 is a kind of free-cutting martensitic stainless steel, which can be strengthened by heat treatment. The strength and machinability of 4 16 are better than those of 304 and 3 16, and the friction coefficient is small, but the corrosion resistance is not as good as 304 and 3 16.

Chemical composition (%)

C: ≤ 0. 15

Manganese Mn: ≤ 1.25

Silicon Si: ≤ 1.00

Chromium Cr: 12.0 ~ 14.0

Nickel Ni: It is allowed to contain less than or equal to 0.60% nickel.

Phosphorus P: ≤ 0.06

Sulfur s: ≥ 0. 15

Molybdenum Mo: 0.60% or less molybdenum can be added.

Heat treatment range:

Because the organizational structure is a body-centered cubic structure, the strength will drop sharply at high temperature. But below 600℃, the high temperature strength and creep strength are the highest among all stainless steels.

Heat treatment specification: 1) annealing, slow cooling at 800 ~ 900℃ or rapid cooling at about 750℃; 2) quenching oil cooling at 920-980 DEG C; 3) Tempering at 600 ~ 750℃ and rapid cooling.
