We produce screws, stud bolts and nuts ASTM A453 GR660 A286 1.4944 GH2132 1.4980 Square Nutmaterial.It is a precipitation hardening steel heat resistant, recommended in case of high mechanical resistance and corrosion resistance up to 700°C. It is suitable to be used in jet engines, turbines, gears, paddles, nuts, bolts, spring washers and other devices that require high temperatures resistance.
The corrosion resistance of ASTM A453 GR660 A286 1.4944 GH2132 1.4980 Square Nut is excellent up to 700°C. The oxidation resistance is good up to 800°C in current “on-order” conditions and up to 980°C in fitful “on-order” conditions.
ASTM A453 GR660 A286 1.4944 GH2132 1.4980 Square Nut can be protected arc welded or arc welded in inert atmosphere. We recommend soluble not aged condition. Soluble operation up to 980°C lasting 1 hour and rapid cooling (by air or by water). Precipitation aging at 720°C lasting 16 hours. Forging gap 1150°C up to 1050°C avoiding to go down 930°C. The warping resistance is higher than the austenitic steels one.
Advantages / Features:
Our company has purchased steel from several large steel groups , such as Hangzhou Steel Mill, Shanghai Bashan Steel Mill, Beijing Shrugging Steel Mill whose steel have good mechanical properties and stability of chemical component. it keep the bolt to be of high strength
2. Manufacture Procession
First, we have our own High-precision Digital Machining center for mould making in special Mould Workshop, excellent mould make product beautiful appearance and its size accurately.
The second, we adopt blasting procession, removing Oxidation surface, make the surface to be bright and clean and uniform and beautiful.
The third, in heat treatment: We use the Controlled-atmosphere Automatic heat treatment Furnace, we also have four mesh belt convey furnaces, Can deal with the products in different sizes keeping the non-oxidation surface
3. Quality Control:
The quality control is strictly performed from buying raw materials in warehouse to different machining procession and to final packing. We have Magnetic Powder Detector, Material Testing Machine, Metallographic Microscope, such testing instruments, guarantee product high quality and beautiful appearance.
4. Production Capacity
Single bolts, every month can produce 5000 Tons.
