201 Stainless steel J series models, differences, performance

Today, take you to understand the models, differences and performance of 201 stainless steel J series.

Description:
201 stainless steel, also known as austenitic stainless steel, its biggest feature is the low nickel content, the addition of manganese, nitrogen, copper and other elements in the steel instead of some nickel, control the strong impact of material properties of carbon and sulfur, etc., with a relatively low cost to obtain high-strength steel. It is resistant to atmospheric, steam and water and other weak medium corrosion characteristics, as well as acid, salt, alkali and other chemical erosion corrosion characteristics. Because of its high density, polishing without bubbles, no pinholes, high cost performance characteristics, widely used in kitchen equipment decoration surface. However, because the manganese content of 201 stainless steel is high, it is easy to rust after heating or contact with strong corrosive substances, so it is generally used in non-high temperature and low corrosion environment.

Type:
Because 201 stainless steel material contains less nickel, high hardness, difficult to process, easy to break in the process, so the steel mill improved the composition on the basis of 201 stainless steel, produced a 201J series of stainless steel material, reduce the nickel element, add the copper element, can make the steel softer, easy to process, not only reduce the cost of steel, but also meet the market requirements. 201 stainless steel due to the composition and application of different fields, so produced J1, J2, J3, J4, J5 five types.
 

Difference:
The nickel and chromium content of 201J series stainless steel is not particularly different, the biggest difference is the copper content and carbon content. The higher the copper content, the softer the material, the easier it is to process, and the higher the price. The copper content from high to low is J4, J1, J3, J2 and J5. The order of carbon content from high to low is J5, J2, J3, J1, J4; The order of hardness from high to low is J5, J2, J3, J1, J4; The price from high to the end is high copper J4, then J1, J3, J2, J5.
 

Tensile properties:
The quality of copper is soft, in addition to chromium and nickel in stainless steel to increase corrosion resistance, more importantly, it can determine the tensile properties and ductility of stainless steel. J2 contains 0.3% copper, belongs to the low copper material, not suitable for stretching, is the current market generally used plate material, only to ensure 90 degrees of turn, can not planing, can not stretch; J1 contains 0.8% copper, which is a medium copper material, suitable for ordinary shallow stretching and small Angle types of stretched products, such as sinks, bathrooms and so on. J4 is a high copper material, containing 1% copper, belongs to the 201 stainless steel series of the relatively high-end type, suitable for deep drawing and deep drawing products, small Angle types, such as kitchenware, etc., is a professional 201 stainless steel drawing material.
