Heat Treating 420 430 Stainless Steel Seamless/welded Polished Tube/pipe

As a representative steel of ferritic steel, the thermal expansion of 430 stainless steel is low, whats more,its formability and oxidation resistance are excellent. Application area: Automobile exhaust pipe,outdoor decorating,home appliance,etc. Chemical composition(WT%) (C) :≤0.12 (Si) :≤0.75...

Description

Stainless steel decorative tube is also called stainless steel welded pipe, referred to as welded pipe.The tube is made up by using steel or steel band through the machine and die after the formation .The technology of welded steel pipe production is simple, high efficiency.The specifications are various and the fund of equipment is low but the general strength is lower than seamless steel pipe.

As a representative steel of ferritic steel, the thermal expansion of 430 stainless steel is low, whats more,its formability and oxidation resistance are excellent.

Chemical composition(WT%)

(Si) :≤0.75

(Mn) :≤1.00

(Cr) :16.0 to 18.0

(P) :≤0.040

(S) :≤0.030

(Ni) : ≤0.60

Physical property

tensile strength:≥451MPa

Yield strength:≥206MPa

Elongation:≥22%

Application

This 430 stainless steel is used for a variety of household and industrial applications such as screws, machinery parts, car headers, and food-handling equipment.

Precautions

1. Relative to 304, the tensile properties and welding performance are poor;

2. Because it is ferritic stainless steel, the strength is relatively low, and the work hardening ability is also low. It should be noted when selecting and using;

3. After the drawing process, the surface will appear ridging in the direction of rolling, which brings great difficulty to the polishing operation.
