As everyone knows, stren>δ®★gth property class for stud bolt♣★s are 8.8, 9.8, 10.9 and 12.9. An•γd the main materials aφ♦™'re mostly Quenched and ™↕"tempered mid-carbon steel ∞<or mid-carbon alloy σ↔≥≥steel.

    As the dev✔÷©§elopment of automobile, machinery,♠₹✔​ construction, renewable energy in≠"÷dustries,  Fastene​←rs, including stud, bolt,nεπ">ut,etc, are required to be more fitablΩ±e. Fasteners need to have more st₹δress resistance performance, and more ↔♦lightened at the sam¥δ↕×e time.

    Since fasteners provid∞δ¥e the function in machinates ‍§✘as connection, fasten, p↓<osition, seal, besides↕©♠  simple positioning wδ∞☆ork, fasteners also need to be tigh"$tened. As a result, faste&€♥ners bear a static tensi£¥≈le load, which will bring loose or bre♠ ak to the fasteners.

Research and development for high-<♣duty steel stud bolt

Improve bolts properti↔γ es

    Reduce sulfur and phoσ∞sphor composition in stee♣✔‌ls. Reducing S compositi↔π←±on will improve deformatio&<™n rate, and reducing Pφ✘ε  composition will impro←☆ve resistance ability. Es εpecially when S composition less t≤♠↑han 0.005%, properties will be much £∑≈​obvious.

    Raw materβ€ials of LT bolt are a ↓¥✘ll special composition,λ" λ with less sulfur and pho☆↓÷sphor.Si, Mn, Cr com"σ↓£positions are all more fε$itable for heat-treatment ₽'Ωproducers, which will affect Ω∞on finished bolt with high hardness, a±φ nd stabilization. 

Reduce Production Costs← '

    Promising it's pr✘™±oducts quality , to be more compe±¥&titive in the market, Anyang L∏φ‌ongteng Heat Treatment Mate£€&≤rial Company require its se☆←<Ωlf to reduce production λ←♠costs. We choose 42CrMoA, 35CrMo δ&steel grade as raw materials, ±πδ₽which are more efficient<Ω​£ on annulling, quenching ∏ ✔"and tempering. 

Advanced Heat-treatment ♥≥₩πTechnology

    Anyang Longteng H∑✘≠eat-treatment MateriaΩ"l Company has its own special heat-tre​®¶atment lines which are fitable for dγε≠☆ifferent diameters. Our professio₹'nal team obtain the technique to∞§∞ control and slight change ♦÷the heating temperatures. All≤÷♥ the production lines are generated&♠ by electric power from our ro€πof solar panels, that is renewa>©ble and green.

    As a  China h£​igh quality fastener manuf≠ acturer and supplier,§$↔ Anyang Longteng Heat Treatment Materiλ↑≤al Co.,Ltd keep one develoε♦•ping it's technology and competitiveneα©γφss. Ultra-high strength bolt researc®×∏h is one of our most importa® $≈nce studies, and we believe our dedicatβλΩ↑ion will bring benefits to the indusπ&♠tries.
