In the landscape of modern global manufacturing, high-end sectors such as aerospace, semiconductor chip fabrication, precision medical instruments, automotive powertrains, and cutting tools demand an uncompromising level of material performance. At Alloword Trading (Shanghai) Co., Ltd., we bridge the gap between rigorous metallurgical science and global industrial engineering. By integrating cutting-edge production technology with rigorous quality frameworks, we deliver world-class special metal strips, alloy steels, and ultra-thin precision materials tailored for the most demanding applications.
Ⅰ. Core Manufacturing Equipment & Technical Superiority
To achieve exceptional dimensional accuracy, pristine surface finishes, and tailored metallurgical structures, Alloword relies on state-of-the-art production and processing lines:
1. 20-High Sendzimir Mills: Equipped with advanced AGC (Automatic Gauge Control) systems and ABB control architecture, our Sendzimir mills process ultra-thin, high-hardness strips with thickness tolerances reaching ±0.002 mm.
●Processing Range: Thickness 0.02–1.0 mm, Width 250–450 mm.
●Typical Grades: 4J36 Invar alloy, AISI 301 (EN 1.4310), AISI 631 (PH 15-7Mo), 6Cr13, and high-carbon spring steels.
2. Full-Hydrogen Bell-Type Annealing Furnaces (BAF): Utilizing 99.999% high-purity hydrogen atmosphere protection, our advanced annealing lines ensure superior surface quality, zero oxidation, and homogeneous mechanical properties.
●Performance Metric: For medium-to-high carbon steels and alloy steels, we guarantee a spheroidization rate of ≥95% and intergranular oxidation/surface decarburization of <5 µm.
3. Precision Tension Levelers & Slitting Lines: Utilizing multi-roll tension leveling and high-precision disc slitting with hydraulic locknuts, we control strip flatness and eliminate camber (edge bow to ≤0.3 mm/m), delivering burr-free edges and exact width tolerances (±0.05 mm).
Ⅱ. Comprehensive Product Portfolio & International Standards Mapping
We strictly reject isolated local standards. Every product supplied by Alloword is fully mapped to international equivalents (AISI, ASTM, JIS, DIN/EN) and backed by comprehensive Mill Test Certificates (MTCs) from premier mills (such as Baosteel), validated by SGS/TUV testing.
1. Carbon & Alloy Steels (Precision Strip & Spring Steel)
