Tianjin Shunchen Industrial is a leading steel product manufacturer with 12 years of export experience, specializing in high-performance structural steel materials. Our production base in Tianjin is equipped with 2 fully automatic hot rolling production lines and a national-level material testing laboratory, focusing on R&D and production of high carbon structural steel plates optimized for heavy-load, high-abrasion working conditions.
Unlike ordinary mild steel plates with low carbon content and poor abrasion performance, our products adopt precise smelting composition control and 880-920℃ quenching + tempering process to form a uniform martensitic microstructure, achieving stable hardness and excellent wear resistance without excessive brittleness. Our quality control engineer Zhang Hong, with 11 years of experience in carbon steel material testing, personally supervises the full-process inspection of each batch, ensuring carbon content deviation ≤0.02% and hardness uniformity difference ≤2HRC. All products comply with GB, ASTM, EN and JIS standards, and can provide complete mill test certificates (MTC EN 10204 3.1) and third-party SGS inspection reports.
Real-world Performance Testing
1. Dry Abrasive Wear Test (Third-party SGS Test)
Test Standard: ASTM G65-17 (Dry Sand/Rubber Wheel Abrasion Test)
Test Conditions: 130N normal load, 2000 continuous rotation cycles, standard quartz sand abrasive
Test Samples:
Ordinary mild steel plate (A36 grade)
Standard 1065 grade high carbon plate (as rolled)
Premium 1095 grade high carbon plate (quenched & tempered)
Key Findings:
A36 mild steel: Weight loss 0.82g, wear depth 0.12mm
1065 grade: Weight loss 0.21g, wear depth 0.03mm — 3.9 times more wear-resistant than A36
1095 grade: Weight loss 0.13g, wear depth 0.018mm — 6.3 times more wear-resistant than A36
2. Hardness & Mechanical Property Verification
Tested after standard quenching and low-temperature tempering treatment, core performance indicators are as follows:
1065 grade: Surface hardness 58-62 HRC, tensile strength ≥750MPa, yield strength ≥450MPa
65Mn grade: Surface hardness 59-63 HRC, tensile strength ≥800MPa, yield strength ≥500MPa
1095 grade: Surface hardness 62-65 HRC, tensile strength ≥880MPa, yield strength ≥540MPa
The optimized heat treatment process achieves a balanced match between hardness and toughness, avoiding cracking or chipping under impact loads.
3. Bending Fatigue Life Test
Test Conditions: Repeated bending load, 5Hz frequency, 350MPa stress level, room temperature environment
Test Results:
A36 mild steel plate: Fatigue fracture occurs after 120,000 cycles
1065 grade high carbon plate: No fracture after 580,000 cycles — fatigue life increased by 380%
Real-world User Scenarios & Verified Cases
Case 1:Mining Crusher Liner Project (Australia Mining Equipment Co., Ltd.)
Problem: Problem: The original A36 mild steel liners in ore crushing chambers wore out severely after 3 months of operation, requiring monthly repair and frequent replacement, causing frequent production shutdowns and high maintenance costs.
Solution: Adopt our 1065 grade high carbon structural steel plate (12mm thickness) for crusher liners, with customized quenching treatment to reach 60HRC surface hardness.
Result: After 14 months of continuous operation, the liner wear is only 15% of the replacement threshold, service life extended from 3 months to 18 months, reducing equipment downtime by 75% and annual maintenance cost by 68%. Annual purchase volume reaches 850 tons, with 5 years of ongoing cooperation.
Case 2: Excavator Bucket Wear Plate Project (Shandong Heavy Machinery Co., Ltd.)
Industry: Construction machinery manufacturing
Problem: Excavator bucket edges made of ordinary structural steel had severe abrasion and deformation after 6 months of use in gravel and earthwork projects, affecting digging efficiency and requiring frequent on-site reinforcement.
Solution: Adopt our 1095 grade quenched high carbon plate (16mm thickness) for bucket cutting edges and side wear plates, with tempering process to optimize impact toughness.
Result: After 12 months of field use, the bucket edges show no obvious deformation or excessive wear, service life extended to 30 months, reducing replacement frequency by 70% and saving over 3.2 million yuan in annual component costs for the client.
Case 3: Precision Spring & Blade Manufacturing Project (Jiangsu Precision Machinery Co., Ltd.)
Industry: Precision component manufacturing
Problem: Ordinary medium carbon steel plates could not meet the hardness and elastic stability requirements for high-stress springs and industrial cutting blades, leading to 8% product rejection rate and short service life of finished goods.
Solution: Adopt our customized 65Mn grade high carbon plate (8mm thickness), with strictly controlled sulfur and phosphorus content and ultra-fine grain rolling process to ensure uniform material performance.
Result: Finished spring products have 30% higher elastic fatigue life, and cutting blade edge retention increased by 45%. Product rejection rate dropped from 8% to 1.2%, helping the client successfully expand high-end European market share.
