Product description

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


Corrosion Resistance

Grade 430 has good resistance to a wide variety of corrosive enviornments, including nitric acid and some organic acids. It attains its maximum corrosion resistance when in the highly polished or buffed condition. In general its resistance to pitting and crevice corrosion resistance is close to that of grade 304. Stress corrosion cracking resistance of Grade 430 is very high, as it is for all ferritic grades.


Like other high-sulphur free machining grades 430F has much reduced resistance to pitting and crevice corrosion compared to its non-free machining equivalent.


Heat Resistance

Grade 430 resists oxidation in intermittent service up to 870°C and to 815°C in continuous service. This grade may become brittle at room temperature after prolonged heating in the 400-600°C range. This effect can be eliminated by annealing.


Application 

Decorating, household appliances, CD rod,bolts and nuts.


Chemical Composition(WT%)

C ≤ 0.12

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%

The normal OD of 430 stainless steel rod bar is from 4mm to 100mm, the usual length is 4m and 6m.

Usually, it only takes 3 working days for us to make delivery if the products are ready in stock.

Of course, unusual size can also be customized according your request.


What is food grade stainless steel?

The food grade stainless steel must control the composition of Mn, some 201 and 202 stainless steel has more than 5.5% Mn composition, so they are not very suitable for making tableware. 430 and 304 stainless steel is very suitable for making tableware because their Mn composition is low. So food grade stainless steel means low Mn composition.


Characteristics and Processing Technology

1D-surface has discontinuous granular, also known as fog surface. Processing technology: Hot-rolled + annealing shot pickling + cold rolling + annealing pickling.

2D-is slightly lustrous and silvery white. Processing technology: Hot-rolled + annealing shot pickling + cold rolling + annealing pickling.

2B-is silvery white and has a better gloss and flatness than the 2D surface. Processing technology: Hot rolled + annealing shot pickling + cold rolling + annealing pickling + tempering rolling.

BA-surface gloss is extremely good, has the very high reflectivity, like the mirror surface. Processing technology: Hot rolled + annealing shot pickling + cold rolling + annealing pickling + surface polishing + tempering rolling.

No. 3-Has a good gloss, the surface is coarse-grained. Processing technology: The 2D product or 2 B with $number abrasive material (JIS R6002) for polishing and rolling.

No. 4-Has a good gloss, the surface of fine lines. Processing technology: The 2D product or 2B with 150~180 abrasive material (JIS R6002) for polishing and rolling.

HL-is silvery gray and has a hairline stripe. Processing technology: The 2D products or 2B products with appropriate particle size of the abrasive material for polishing to make the surface continuous grinding.
