Product description

Wholesale ASTM AISI JIS DIN EN Inox Welded 430 Stainless Steel Pipe
 430 is equivalent to our domestic 1Cr17 stainless steel. 430 contains carbon of 0.01% and chromium around 17% .
 Characteristics and Applications: general steel with good corrosion resistance, and also for building interior decoration, heavy oil burner components, household appliances, household electric apparatus.


Characteristics
 1) Excellent deep drawing performance, similar to 304 steel;
 2) It has strong corrosion resistance to oxidizing acid and certain corrosion resistance to lye and most organic acids and inorganic acids; and its stress corrosion resistance and cracking capacity are better than that of 304 steel grade.  
 3) The coefficient of thermal expansion is lower than that of 304 steel, and the oxidation resistance is high, which is suitable for heat-resistant equipment.
 4) Cold-rolled products have good appearance and good brightness.
 5) Compared with 304, the price is cheap and it can be the alternative steel for the 304 steel.

Application Range of 430 Stainless Steel Pipe
 It is mainly used for high polishing decoration in mild atmosphere, such as gas stove surface, home appliance parts, tableware, building interior decoration, washing tank, washing machine barrel and so on.

Treatment Mode and Applicable State of 430 Stainless Steel Pipes

1.Heat Treatment

2.Melting point: 1425~15100C.

Annealing: 780~8500C. 

3. Using State
Annealing State: NO.1,2D,2B,N0.4,HL,BA,Mirror and various other surface treatment states

Attention

1.Compared with 304, its tensile properties and welding properties are poor.

2.Due to being ferrite stainless steel, the strength is relatively low; the work hardening ability is also low; we should pay attention to its using.

3.Strip defects like ridging in rolling direction will appear on the surface after drawing, which brings great difficulties to polishing.
