II. Core Properties of Deposited Metal
1. Chemical Composition (%)
| Chemical Composition | Standard Limit | Actual Sample Value | Core Function |
|---|---|---|---|
| Carbon (C) | ≤0.03 | 0.025 | Low-carbon design reduces carbide precipitation, prevents intergranular corrosion, and improves weld corrosion resistance |
| Manganese (Mn) | 1.0-2.5 | 1.63 | Optimizes weld bead fluidity, enhances weld toughness and structural strength |
| Silicon (Si) | 0.3-0.65 | 0.43 | Deoxidizes and removes gas, reduces the risk of porosity defects, and improves weld density |
| Chromium (Cr) | 19.5-22.0 | 20.05 | Forms a passive film, resists oxidation and chemical medium erosion, and is a core corrosion-resistant element |
| Nickel (Ni) | 9.0-11.0 | 10.2 | Cooperates with chromium to enhance corrosion resistance and improves the low-temperature toughness of the weld |
| Copper (Cu) | ≤0.75 | 0.02 | Assists in improving corrosion resistance, with composition control accuracy far exceeding the standard |
| Molybdenum (Mo) | ≤0.75 | 0.02 | Avoids affecting the stability of the welding process and ensures uniform weld bead formation |
2. Mechanical Properties
| Performance Indicator | Standard Requirement | Actual Sample Value | Performance Advantage |
|---|---|---|---|
| Tensile Strength | ≥550MPa | 610MPa | Can withstand higher tensile loads, suitable for high-strength structural welding |
| Elongation | ≥35% | 41% | Excellent plasticity and toughness, reducing the risk of stress cracks after welding |
III. Core Product Features
Quality Assurance: Certified by ISO 9001-2008, CE, and SGS. Full-process quality control from raw material selection to finished product inspection ensures stable performance of each batch of welding wire.
Strong Process Adaptability: Supports two mainstream welding processes (MIG/TIG) and covers diameter specifications from 0.8mm to 1.6mm, meeting the needs of different scenarios such as fine thin-wall welding, conventional structural welding, and multi-pass welding.
Extreme Temperature Resistance: The weld can work stably in the temperature range of -195℃ to +350℃, without brittleness at low temperatures and stable performance at medium temperatures. It is suitable for special working conditions such as low-temperature storage tanks and medium-temperature pipelines.
Low-hydrogen Welding Solution: When used with BOHLER BB 802 fluorine-based sintered flux, it can achieve low flux consumption and low-hydrogen welds, significantly reducing the risk of delayed cracks. It is suitable for key structures such as pressure vessels and chemical equipment.
Flexible Service Solutions: OEM customization is supported, and packaging can be adjusted according to needs. Free samples are provided to facilitate the verification of welding effects before bulk purchase. Fast delivery within 25 days and multi-port shipping cover domestic and international markets.
IV. Application Scenarios
| Application Field | Specific Scenarios | Adaptation Reasons |
|---|---|---|
| Stainless Steel Welding | Multi-pass welding, flat butt welding, and fillet welding of 1.4306 (304L) low-carbon austenitic stainless steel | The weld bead has a smooth appearance, no slag residue, easy slag cleaning, and matches the compositional characteristics of 304L stainless steel |
| Equipment Manufacturing | Food machinery, medical equipment, new energy energy storage tanks | Low carbon and low impurities, avoiding metal ion precipitation, and meeting the requirements for cleanliness and corrosion resistance |
| Pressure Equipment & Chemical Industry | Pressure vessels, chemical pipelines, storage equipment for corrosive media | High tensile strength (610MPa), low-hydrogen welding solution prevents cracks, and resists corrosive environments |
| Low-temperature/Medium-temperature Engineering | LNG storage tanks, refrigeration equipment, medium-temperature heating pipelines | Works stably in the temperature range of -195℃ to +350℃, adapting to extreme temperature working conditions |
V. Market Positioning
