321 stainless steel strip

Grade 321 is the grade of choice for applications in the temperature range of up to about 900°C, combining high strength, resistance to scaling and phase stability with resistance to subsequent aqueous corrosion.

Type	Hardness		Tensile Strength		Properties	Application
	Cold- rolled	Hot- rolled	Cold- rolled	Hot- rolled
321stainless steel strip	530	570	1760	about 1800	Ti element added into 321 stainless steel to prevent grain boundary corrosion; suit for use under 430 ℃ -900 ℃ temperature.	Wide use in machinery, electronics, high-tech product parts, auto parts, kitchen appliances,washer, spring shrapnel and other metal stamping industries.( All materials are standard, providing material evidence and SGS report.)

321 stainless steel strip are used because they are not sensitive to intergranular corrosion after heating within the carbide precipitation range of 425-850°C. A limitation with 321 stainless steel is that titanium does not transfer well across a high temperature arc, so is not recommended as a welding consumable.
