| High Light | ASME SA423 Grade 1 ERW tubing ，Corten steel tubing for heat exchangers ，weathering steel alloy tube | ||
Our ASME SA423 Grade 1 ERW Tubes are manufactured to the stringent requirements of the ASME Boiler
and Pressure Vessel Code, Section II. This grade represents a cost-effective, high-performance carbon steel
solution specifically designed for high-temperature and high-pressure service in boilers, superheaters, and
heat exchangers. The Electric Resistance Welding (ERW) process ensures excellent dimensional consistency
and a reliable, homogenous weld seam, making Grade 1 ERW tubes a proven equivalent alternative to seamless
tubes in many demanding applications. Strict quality control guarantees compliance with all chemical, mechanical,
and dimensional specifications.
The controlled chemical composition of ASME SA423 Grade 1 is fundamental to its weldability, formability, and strength at elevated temperatures. The typical analysis is shown below:
| Element | Composition (% by Weight, Max Unless Noted) | Key Role |
|---|---|---|
| Carbon (C) | 0.27 max | Strength, hardenability |
| Manganese (Mn) | 0.93 max | Strength, hardenability, deoxidation |
| Phosphorus (P) | 0.035 max | Impurity (reduces toughness) |
| Sulfur (S) | 0.035 max | Impurity (causes hot shortness) |
| Silicon (Si) | 0.10 min - 0.35 max | Deoxidation, strength |
| Material Base | Carbon Steel | Primary constituent |
| Carbon Equivalent (CEV) | ≈ 0.40 - 0.50 (Typical) | Predicts weldability (CEV = C + Mn/6) |
ASME SA423 Grade 1 ERW is recognized globally under these comparable standards:
| Standard | Equivalent Grade | Material Type | Notes |
|---|---|---|---|
| ASME | SA423 Grade 1 | ERW Tube | Primary specification |
| ASTM | A423 Grade 1 | ERW Tube | Identical material specification |
| EN / DIN | Not Direct Equivalent | - | Closest might be P265GH, but differs |
| JIS | STB 410 | ERW Tube | Similar application, check specifics |
| Common Name | Boiler Tube | Carbon Steel | Industry terminology |
ASME SA423 Grade 1 ERW tubes deliver reliable strength and ductility required for pressurized systems:
| Property | Requirement (ASME SA-423) | Typical Value Range | Test Method |
|---|---|---|---|
| Tensile Strength | ≥ 325 MPa (47,000 psi) | 380 - 450 MPa | ASTM A370 |
| (55,000 - 65,000 psi) | |||
| Yield Strength (0.2% Offset) | ≥ 180 MPa (26,000 psi) | 210 - 280 MPa | ASTM A370 |
| (30,000 - 40,000 psi) | |||
| Elongation (in 2") | ≥ 30% | 35% - 45% | ASTM A370 |
| Hardness | Not Specified | ≤ 72 HRB (Typical) | Rockwell B Scale |
| Material Characteristic | Ductile Carbon Steel | Good Formability | - |
Our Grade 1 ERW tubes are produced to meet or exceed standard dimensional tolerances:
| Dimension | Tolerance (Based on ASME SA-423 & Common Practice) | Standard Reference |
|---|---|---|
| Outside Diameter (OD) | ± 0.8% or ± 0.10 mm (±0.004"), whichever is greater | ASME SA-450 |
| Wall Thickness | +20% / -0% (Common Mill Practice for ERW) | ASME SA-450 |
| Length | +3 mm (+1/8") / 0 mm (0") for Random Lengths | Customer Spec / Std |
| ± 3 mm (±1/8") for Cut Lengths | Customer Spec / Std | |
| Straightness | ≤ 0.2% of length (e.g., 3mm/m or 0.036"/ft) | Industry Standard |
| Weld Integrity | Mandatory Non-Destructive Testing (NDT) | ASME SA-423 |
Leveraging its carbon steel composition and certified performance, SA423 Grade 1 ERW is ideal for:
