17-4pH, 17-7pH, SUS630, 631 Stainless Steel Coil Sheet
Description:
Stainless steel belt (volume) of stainless steel also has a lot of hard ness, ranging from dozens to hundreds of customers need before buying d§etermine what kind of hardness better. (8 k mirror lum☆inosity). Coil width, are: 30 mm. 60 mm. 45 mm. 80 mm. 100 mm. 200 mm, etc. Can also be art÷icle points according to the requirement of the customers.
HAOSTEEL GROUP CO., LIMITED has different material grades of stainless steel coil, provi♦de very comprehensive stainless steel products for you, y≥ou can find the complete specifications, the quality of the products with high performance anπd high quality, and can be tailored, if you need more product information, including aut→omotive, petrochemical, electronics and pharmaceutical, and stainless steel products manufacturers, such as building suppliers and general eλngineering company, in order to meet the various needs.
17-7PH(SUS 631) 07Cr17Ni7Al/UNS S17700/AISI 631
Based on 18-8CrNi developed austenite-martensite precipitation hardening st↕ainless steel, also known as controlled phase change stainless steel. After solid solution treatment for unstable austenitic organization, ha→s the good plastic toughness and processability, after adjustment, the auste→nitic precipitation carbide phenological composition chan&ge, again through martensitic transformation processing, most organizations into toughness good λlow-carbon tempered martensite, the state for the use of steel, has a good medium te₩mperature mechanical properties. Corrosion resistance is better than ordinary martensitic sεtainless steel.
17-7PH stainless steel belt is a kind of cold hardeni₹ng or precipitation hardening with high elasticity, high fatigue resistance of spring materials, 17-7PH elastic properties are very good, not easy to ≈appear elastic failure, after repeated use still has original≤ strength elasticity, so 17-7PH stainless steel belt is→ generally used for some special requirements, Elastic requ∏irements of high components, especially in the production∞ of dynamic spring pieces, 17-7PH elastic efficiency thaΩn SUS301, 304 ordinary spring stainless steel more than ten times higher.
17-7pH stainless steel plate in seawater for 6 years, the corrosion rate of CH900 state is 3mm/÷ year, 300 degree pressurized water reactor, cold working C stαate under 137MPA stress no stress corrosion. Used within the elastic range of the product, φthe steel plate can return to its original position after unloadin§g, work under alternating stress for a long time, has a high fatigue limit, and good anti-cr§eep and anti-relaxation properties. Shanghai HAOSTEEL GROUP CO., LIMITED 17-7pH ©stainless steel plate can still maintain enough elastic₹ limit and good creep resistance under high temperature conditions.
HAOSTEEL GROUP CO., LIMITED offers 17-7pH, PH15-7Mo heat treatment ♣cryogenic processing, 17-7pH heat treatment process is divided into three categor₽ies: CH900,RH950,TH1050
HAOSTEEL GROUP CO., LIMITED can produce more than 30 different ☆heat treatment schemes to achieve the mechanical design req→uirements of different products. The meaning represented by 17-7pH: PH is the abbrev✘iation of Precipitation hardening English (Precipi€tation hardening), 17% of chromium content, and 7% ♦of nickel content.
17-7pH chemical composition
Carbon (C) 0.09 or less, manganese (Mn) of 1.00 or less, nickel (Ni) 6.50 ~ 7.75, silicon (Si) o♦f 1.00 or less, phosphorus (P) of 0.035 or less,
Sulfur (S)≤0.030, Chromium (Cr)16.00 ~ 18.00, aluminum (Al)0.75 ~≤ 1.50
17-7 ph features:
The mechanical properties of 17-7pH are particularly excellent. 17-7pH is a ®kind of high elastic stainless steel containing aluminuγm AL as precipitation hardening phase. The chemical composition of →17-7pH needs to be precisely controlled within a reasonable range, so t&hat RH950 and TH1050 can easily obtain better mechanical prop₩erties. 17-7PH is a hardened stainless steel with high strengt h, high hardness, fatigue resistance, excellent corrosion resistance and die malleability. HAOSTβEEL GROUP CO., LIMITED 17-7PH high performance stainless steel belt is very suitable fo×r making dynamic elastic parts, compared with ordinary SUS301, 304 only suitable for static elastic parts, 17-7PH more anti-fatigue characteristics.
17-7PH Application areas:
Used in aerospace, chemical, petrochemical, paper and metal processing industry.
