Lork Professional Supply S66286/a-286 Steel Sheet 660 Stainless Steel Plate¹

Product Description Product Description IntroductionLORK is a special stainless steel manufacturer with 20 years of manufacturing experience. Alloy 660 is a precipitation hardening austenitic stainless steel known for its impressive strength at high temperatures up to 700°C. Also sold under the names, UNS S66286, and A-286 alloy, Alloy 660 gains its strength from a high degree of uniformity. It has an impressive yield strength minimum of 105,000 psi and is commonly used in high temperature fastening and bolting materials.Stainless Steel a-286 Applications- Gas turbine forgings, - Fasteners, - Superchargers, - Cryogenic equipment, - Missile components, - Corrosive deep well hardware - Jet engines.Cold workingSuper alloy A-286 is capable of being readily cold worked and a solution anneal heat treatment is recommended when this alloy is work hardened due to severe cold forming. This solution anneal heat treatment will thus enable softening of super alloy A-286.WeldingWelding methods used for stainless steels are also recommended for super alloy A-286. The area to be welded should be clean. Post welding heat treatment or preheating is not recommended for this alloy. Better welding results can be obtained when this alloy is solution annealed.ForgingHeavy forging and light forging are suitable for super alloy A-286. Heavy forging is carried out between 1010-1204°C (1850-2200°F) and light forging between 871-1010°C (1600-1850°F).FormingConventional forming methods are used to readily hot or cold form super alloy A-286.MachinabilityConventional machining techniques are used to readily machine super alloy A-286. This machining process involves turning, drilling and milling. In the turning operations, the usage of cemented carbide tools is recommended for high cutting rates.AgingSuper alloy A-286 is first solution heat treated at 982°C (1800°F) before the aging process. Aging takes place for 16 h at 718°C (1325°F) after which this alloy is cooled in air.HardeningSuper alloy A-286 is hardened by the cold working process and is also capable of being age hardened due to the presence of titanium in this alloy.Heat TreatmentSuper alloy A-286 is solution annealed at 982°C (1800°F), oil quenched, held for 16 h at 718°C (1325°F) and finally cooled in air. This heat treatment improves the strength of super alloy A-286.Stainless Steel a-286 Chemical CompositionElementContent (%)Iron, Fe54Nickel, Ni25.5Chromium, Cr14.8Titanium, Ti2.13Molybdenum, Mo1.30Manganese, Mn1.0Silicon, Si0.50Vanadium, V0.30Aluminum, Al0.18Carbon, C0.040Phosphorous, P0.020Sulfur, S0.015Boron, B0.0060Stainless Steel a-286 Mechanical PropertiesPropertiesMetricImperialTensile strength1035 MPa150100 psiYield strength (@strain 0.200%)759 MPa110000 psiElongation at break25%25%Reduction of area40%40%Hardness, Brinell (estimated from Rockwell C value for Brinell test with 3000 kg load/10 mm diameter ball)304304Hardness, Knoop (estimated from Rockwell C value)330330Hardness, Rockwell C3232Hardness, Vickers (estimated from Rockwell C value)318318Stainless Steel a-286 Other DesignationsAISI 660AMS 5525AMS 5726AMS 5732AMS 5734AMS 5731AISI 662AMS 5737AMS 5804AMS 5895AMS 5853AMS 5805AMS 5858DIN 1.4943SPS M250DIN 1.4944GE B50T81GE B50T12GE B50T1181ASTM A453 Grade 660ASTM A638 Grade 660    Available Sizes And Specifications 660 stainless steel plate sizes and specificationsGrade660Cold rolled stainless steel plateThickness: 0.3mm- 16.0mm, Width: 1000mm - 2000mm,Length: as requirements, Surface: 2B/BA/SB/8K/HL/1D/2D etcHot rolled stainless steel sheetThickness: 3.0mm - 300mm, Width: 1000mm - 3000mmLength: as requirements, Surface: No.1/picklingStandardASTM A240/A480, ASTM B688, ASTM B463/SB463, ASTM B168/SB168, ASTM B443/SB443/B424/SB424B625/SB625 B575/SB575, JIS G4303,BS 1449, DN17441, G4305Stainless steel plateThickness: 8.0mm - 300mm, Width: 1000mm - 3000mmLength: as requirements, Surface: No.1/pickling DetectionProcessing Packaging & ShippingCompany ProfileFAQQ1: Do you accept the trial order ?A1: Yes,if we have the exactly size in stock.we can delivery even 1 piece/meter .Q2: Can I have free sample before making orders?A2: Yes,we can supply free sample as requirement,but buyer needs to pay the freight charges ,the freight fee will return to buyer after making order.Q3: How do you control the quality ?A3: MTC and PMI will be sent before shipment,any 3rd party inspection if need .Q4: How about your delivery time ?A4: Generally delivery time is 15 working days .Q5: How can I quickly get the price list ?A5: Directly click "chat now" or send us email with detail specifications,you will get the official price list in 1 hour .
