JX-21JG376-D14-M6-43-ST, Carbon steel machined parts for medical equipment, surface treatment with environmentally friendly black zinc plating

Applications:

1, after tempering treatment is generally used for the manufacture of higher strength requirements, not very large force machined parts, forgings, stamping parts and nuts, pipe fittings, and other parts;

2, after carburizing treatment is generally used for the surface wear-resistant, core impact-resistant heavy-duty parts, gas wear resistance than quenched + surface quenching high.Provide CNC turning processing, CNC turning and milling compound processing, CNC processing, automatic turning processing, cutting processing, machining, hardware processing, non-standard parts precision processing, stainless steel parts precision processing, industry professional equipment processing, other mechanical processing, casting machining, thread cutting processing, metal processing, etc.

Characteristics:

1. a high-quality carbon structural steel, medium carbon steel, carbon content of 0.4% or more, not high hardness easy to cut and process, usually by hot rolling or cold rolling forming;

2. tensile strength > 686MPa, yield strength > 490MPa;

3. tempered hardness between HRC20-HRC30, tempered to ensure superior mechanical properties, but the surface hardness is low, not wear-resistant, and cutting performance will be reduced;

4. hardness between HRC55-58 after quenching, the limit value can reach HRC62, but will reduce the original mechanical properties;

5. carburizing treatment can improve surface wear resistance;

6. Generally use quenching + surface quenching to adjust the hardness of the surface treatment of the parts, making a good overall performance.

Commonly used surface treatment, heat treatment methods: 

1. quenching;

2. quenching + surface quenching;

3. carburizing;

4. black zinc plating;

Disadvantages:

1、Surface is easy to rust, rust resistance is much worse than stainless steel and aluminum, there are clean room requirements occasions can not be used.
