201 Stainless steel J series models, differences, performaγnce

Today, take you to understand the models, differences and performance of 201 stai nless 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, nπitrogen, copper and other elements in the steel instead of some nickelπ, control the strong impact of material properties of carbon and sulfur,Ω etc., with a relatively low cost to obtain high-strength steel. It is res&istant to atmospheric, steam and water and other weak medium corrosion characteristics, as w↔ell as acid, salt, alkali and other chemical erosion corrosion cha♥racteristics. Because of its high density, polishing without bubbles, no pinholes, hi€gh cost performance characteristics, widely used in kitchen equipment decoration surfa>ce. However, because the manganese content of 201 stainless steel is high, it is easy toφ 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 nick↓el, high hardness, difficult to process, easy to break in the proce∑ss, so the steel mill improved the composition on the basis of 201  stainless steel, produced a 201J series of stainless steel material, redu ce 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 applica"tion of different fields, so produced J1, J2, J3, J4, J5 five t₩ypes.
 

Difference:
The nickel and chromium content of 201J series stainless ste$el is not particularly different, the biggest difference is the copper content and ca∑rbon content. The higher the copper content, the softer the <material, the easier it is to process, and the higher the price. The copper cont×ent 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 highε 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 sta✔inless 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 curreεnt market generally used plate material, only to ensure 90 degrees of turn, c₽an not planing, can not stretch; J1 contains 0.8% copper,↔ which is a medium copper material, suitable for ordinary shallow stretching and small A₹ngle types of stretched products, such as sinks, bathrooms and so on. J‌4 is a high copper material, containing 1% copper, beγlongs to the 201 stainless steel series of the relatively high-end type, suitable for deep draw₩ing and deep drawing products, small Angle types, such§ as kitchenware, etc., is a professional 201 stainless steel drawing materialβ.
