UNS S15500 stainless steel name: precipitation sclerosis stainless steel standard: AISI, ASTM type: UNS S15500 UNS Numbers: S15500 "UNS S15500 characteristics and application: UNS S15500 is hardened martensitic stainless steel precipitation, processing manufaturability and the mechanical performance, resistance to general corrosive environment, good strength, toughness, hardness and transverse ductility and corrosion resistance and 304 stainless steel. UNS S15500 may be used to solve or heat treatment conditions for the treatment of various performance. In all can reach under the condition of processing, however, in H1150M this condition can have the best service life. Areas of application: aerospace, aircraft parts and components manufacturing high pressure valve and corrosive environment, groove, fasteners, equipment and equipment. "UNS S15500 chemical composition (1) : carbon C: more than 0.07 Mn Mn: more than 1.00 silicon Si: more than 1.00 chromium Cr: 14.0 ~ 15.5 Ni Ni (2) : 3.5 ~ 5.5 P P: more than 0.04 sulfur S: 0.03 or copper Cu: 2.5 ~ 4.5 niobium + tantalum Nb + Ta: 0.15 ~ 0.45 note: (1) a single numerical unless otherwise stated, all is high; (2) used in some of the process, some models austenitic stainless steel contain nickel content just above table must be shown in numerical; (3) optional; (4) the highest including TA content is 0.10%; (5) the highest content is 0.75%; 6 the highest content is 0.70%tion base
High temperature alloy refers to iron, nickel, cobalt as base, can in the 600-1200 ℃ high temperature and must stress under the action of a kind of metal materials long-term work; And it has higher temperature strength, good resistance to oxidation and corrosion resistance, good fatigue performance, the fracture toughness, and other comprehensive performance. High temperature alloy for a single austenitic organization, in all kinds of temperature has good stability and reliability of the organizations use, based on these properties, and high temperature alloy alloying degree is higher, also called "super alloys", it is widely used in aviation, spaceflight, petroleum, chemical industry, ships is a kind of important material. According to the matrix element to points, high temperature alloy and divided into iron base, nickel and cobalt base, high temperature alloy etc. Iron base high temperature alloy using temperature normally only up to 750 ~ 780 ℃, in the higher temperature of the heat used parts, used the nickel and refractory metal based

1;High temperature alloy with high temperature strength.
2;Good resistance to oxidation and corrosion resistance performance.
3;Good fatigue performance, the fracture toughness, plastic.
Organizational characteristics:
High temperature alloy for a single (austenitic) matrix organization, in all kinds of temperature has good stability and reliability of the organization to use.
High temperature alloy quality requirements:
External quality: external contour shape, size accuracy, the surface defect cleaning method.
Internal quality: chemical composition, structure, mechanical and physical and chemical properties.
Mechanical properties: room temperature and high temperature tensile properties and impact toughness, high temperature lasting several creep properties, hardness and high weeks and weeks, creep, fatigue performance under the mutual action of fatigue and the mechanical properties, thermal and corrosion resistance to oxidation.

Company Instoduction:Sichuan Changcheng Special Steel Limited Liability
Company of Pan Steel Group(hereinafter referred to as PCSSC) Iocates in Jiangyou City,Sichuan Province,which former name is Changcheng Steel
Factory of Metallurgical Industry.It's built up in the year of 1965 and put into production in 1972.PCSSC has become one of the large core enterprises in Sichuan province and the important research and manufacture
base for special steel of China.In 1994,Changcheng special Steel Corporation ,the shareholding subsidiary of PCSSC has been listed on Shenzhen Stock Exchange.On June,2004,Pan steel Group reformed Changcheng Special Steel Company formally,and formed Sichuan Changcheng Special Steel
Limited Liability Company of Pan Steel Group.
At present,PCSSC has the annual production capacity to turn out 650,000
tons of special steel and 700,000 tons of finished steel products.It can supply users with 12 kinds of qualitative special steel and metal products
more than 350 grades,over 5000 dimensions on the international or national standard.The products can be widely used in all aspects of aviation,aerospace,shipbuilding,military industry,nuclear power and transportation,machine,petrochemical,medical instruments and so on.And sold to all of the country and exported into USA,Europe and Southeast Asia,etc.Some 34 products have awarded the title of the
National,Ministerial and Provincial level high-quality products.Also,product quality as cold-work mould steel has reached international level.After more than forty years development,PCSSC has grwn
into the important national special steel research and production base and military industry supporting enterprise and become irreplaceable imporyant force in the domains of national defense industry,aviation,aerospace,navigation and nuclear power.
Thereto,top-end products as titanium products and nuclear power tubes have strong market competitions and formed a new economic grow point.PCSSC is one of the three main military products and super alloyed steel production bases of China,which is on a par with the Northeast Special Steel and Special Steel of Bao Steel.It makes great contribution to insist
on self reliance,speed up national befense modern construction,to enhance our capability of independent innovation and insist on self-development to push forward nationalizing major equipment construction.
PCSSC insists the operation policy of pursuing special,holds the philossophy of "I have what you haven't,I expertise what you have",and adhere to the "science and technology enterprises,human resources enterpises,independent creation"idea,and insist on the operation principle"people oriented".The company has gradually formed a corporate identity which is "superior production technology,self-contained specialized equipment,strong technology research and development,high technology content",and realized the strategic objectives to build PCSSC as a maijr military manufacturing base,the domestic first-class Titanium steel bounded type fine steel bases and nuclear power production base.
