JX-21JG404-M4-ST, Carbon steel cross round head knurled thumb screws, surface treatment electroplated with environmentally friendly nickel, electronic and electrical appliance manufacturing, electrical equipment manufacturing applications

Steel nickel plating has no pollution, no heavy metals, long cycle life, and no plating equipment; the plating is a nickel-phosphorus alloy layer with good corrosion resistance and excellent bonding. The plating solution is stable and has a life span of more than 12 cycles, etc. Suitable for various shapes and parts of various steel materials; dense plating, and low porosity, can improve many properties of the material, such as: strengthening the strength, improving hardness, with super corrosion resistance, can exceed the use of stainless steel standards, and can save lot of costs.

Steel nickel plating has the following characteristics:

1. No direct current is required, and it can be plated by chemical reaction, with lower energy consumption.

2, strong corrosion-resistance, the process after treatment of the metal surface for the amorphous layer, corrosion resistance is particularly good.

3、Low porosity of plating layer, good bonding strength, strong corrosion resistance.

4、Great bonding strength, the alloy layer treated by this technology has increased bonding strength with the metal base part.

Material: Steel 1215 Machined Parts

 Manufacturing has a reputation for machining quality parts from 1215 Steel. We can machine intricate parts on our CNC Swiss machines and CNC turning centers. Steel alloy 1215 is a popular free-machining alloy (FMA), ideal for parts that require considerable machining and a bright finish. It responds well to slight bending, threading, and nibbling, but is not ideal for parts that may be subject to very severe fatigue stress.1215 has a machining cost factor of 1.2 when compared to steel 12L14. It possesses better weldability and formability than 12L14. 1215 can be heat treated.

Packing: Inner is Poly foam, out is carton. Then pallet. Carton size: 29*19*19.5CM and 23.5*17.5*8, CM and pallet size is: 215*100*90CM, or as your requirement.
