Carbon Steel Square Washers
Standard:DIN436
Grade:4.8
Material:Q355 steel
Products Description
Product Application
Carbon Steel Square Washers are mainly used to increase the distance between the fastener and the connected parts, protect the surface of the connected parts from damage, and disperse the pressure of the screw cap on the connected parts. Generally, 4.8 grade is more common, usually made of Q235 low carbon steel material, and galvanized.
The difference
The difference between stainless steel square Washers
and carbon steel square Washers
Material and corrosion resistance
usually made of stainless steel (such as SUS304, SUS316), with good corrosion resistance, suitable for environments that need to resist chemical corrosion.
Material and corrosion resistance
Carbon steel square washers made of carbon steel, with poor corrosion resistance, usually require surface treatment (such as galvanizing, painting) to improve its corrosion resistance.
Mechanical properties
Stainless steel square washers have good toughness and strength, and can maintain stable performance under high temperature and high pressure environments.
Mechanical properties
Carbon steel square washers have high hardness, but poor elasticity, which may cause damage to the contact surface.
Application scenarios
Stainless steel square washers are suitable for industries such as petroleum, chemical, metallurgy, and electric power, especially in situations where high temperature, high pressure and corrosion resistance are required.
Application scenarios
Carbon steel square washers are suitable for general industrial applications, but limited use in environments requiring high corrosion resistance.
