Basic Knowledge About Stainless Steel

Do you know how to calculate the weight of stainless steel pipes? Do you know the differences between stainless steel pipes of different materials?

1. Stainless Steel Plate Weight Calculation Formula: Length * Width * Thickness * Specific Gravity = Weight

For example: 1.5mm * 1000mm * 2000mm, 1 * 2 * 1.5 * 7.93 = 23.79 kg

2. Stainless Steel Pipe Weight Calculation Formula: (Diameter - Wall Thickness) * Wall Thickness * Specific Gravity = Weight per meter

For example: 108 * 4mm pipe, (108 - 4) * 4 * 0.02491 = 10.36 kg

3. Differences between 304 and 201 stainless steel pipes:

1. Price difference: 304 is of better quality but more expensive, 201 is of lower quality but cheaper.

2. Composition difference: 304 contains 8% nickel and 18% chromium, 201 contains 1% nickel and 13% chromium.

3. Corrosion resistance difference: 304 has strong corrosion resistance, 201 has weak corrosion resistance.

4. Strength difference: 304 steel has a yield point of 205 MPa and tensile strength ≥ 515 MPa, 201 steel has a yield point of 275 MPa and tensile strength ≥ 520 MPa.
