GB/T 24187 specifies the technical necessities for cold-drawn precision unmarried welded metallic tubes specially used in mechanical applications. those tubes are synthetic to meet strict dimensional, mechanical, and chemical requirements, offering high accuracy and steady overall performance in engineering applications.
The fabric used in GB/T 24187 tubes is normally carbon metal or low alloy steel. these steels are decided on for his or her incredible weldability, mechanical electricity, and floor satisfactory after bloodless drawing. The tubes go through bloodless drawing to improve dimensional accuracy, floor finish, and mechanical residences.
The chemical composition limits for common grades under GB/T 24187 are as follows:
Element | C (Steel Grade) | Mn | Si | P (max) | S (max) | Other Elements |
---|---|---|---|---|---|---|
Typical Grade 1 (e.g. Q195) | 0.06-0.12% | 0.30-0.50% | ≤0.30% | ≤0.035% | ≤0.035% | - |
Typical Grade 2 (e.g. Q215) | 0.12-0.18% | 0.30-0.70% | ≤0.30% | ≤0.035% | ≤0.035% | - |
Typical Grade 3 (e.g. Q235) | 0.12-0.20% | 0.30-0.70% | ≤0.30% | ≤0.035% | ≤0.035% | - |
Property | Q195 Grade | Q215 Grade | Q235 Grade |
---|---|---|---|
Tensile Strength | 270 - 410 MPa | 300 - 440 MPa | 370 - 500 MPa |
Yield Strength | ≥ 195 MPa | ≥ 215 MPa | ≥ 235 MPa |
Elongation (%) | ≥ 26% | ≥ 23% | ≥ 20% |
Hardness (HB) | 110 - 140 | 120 - 150 | 130 - 170 |
GB/T 24187 cold-drawn precision unmarried welded metal tubes are widely utilized in:
equivalent or comparable international requirements and grades consist of:
Chinese Grade | ASTM Equivalent | EN Equivalent | JIS Equivalent |
---|---|---|---|
Q195 | ASTM A513 Gr. 1010 | EN 10305-3 E195 | JIS G3444 STKM 11A |
Q215 | ASTM A513 Gr. 1015 | EN 10305-3 E215 | JIS G3444 STKM 12A |
Q235 | ASTM A513 Gr. 1020 | EN 10305-3 E235 | JIS G3444 STKM 13A |
A: manufacturer,also can do trading.
A: Generally speaking,it is 10-15 days if the goods are in stock,or it is 30-40 days if the goods are not in stock, it is according to quantity.
A: Yes, we could offer the sample for free charge but need pay the cost of freight.
A: Payment<=2000USD, 100% in advance. Payment>=2000USD, 30% T/T in advance ,balance before shippment.
