lz看看是不是这个？ Steel PK11SP (Mat.No. 1.4541, DIN X6CrNiTi18-10, AISI 321) Designation by Standards Brand Name Ravne No. Mat. No. DIN EN AISI PK11SP 914 1.4541 X6CrNiTi18-10 X6CrNiTi1810 321 Chemical Composition (in weight %) C Si Mn Cr Mo Ni V W Others max. 0.08 max. 1.00 max. 2.00 18.00 - 10.50 - - min. Ti=5 x C x 0.7 Description The key feature of 321 stainless is its resistance to intergranular corrosion. It employs titanium as a stabilizing element against chromium carbide formation. This alloy also exhibits strength characteristics superior to those of 304 stainless. Applications Jet engine parts, furnace heat treated parts, expansion joints, turbo superchargers, oil refiners, exhaust manifolds and high temperature chemical production equipment. Physical properties (avarage values) at ambient temperature Modulus of elasticity [103 x N/mm2]: 203, 186 (200oC), 172(400oC) Density [g/cm3]: 7.9 Thermal conductivity [W/m.K]: 14.6 Electric resistivity [Ohm mm2/m]: 0.73 Specific heat capacity[J/g.K]: 0.502 Coefficient of Linear Thermal Expansion 10-6 oC-1 20-100oC 20-200oC 20-300oC 20-400oC 20-500oC 16.0 17.0 17.0 18.0 18.0 Hardening Harden from a temperature of 1020-1100oC followed by water or air quenching. Structure is austenite with small ferrite component. Mechanical properties in solution-annealed condition and reistance to intercrystalline corrosion Hardness: 130-190 HB 0.2 % proof stress: 190 N/mm2 1.0 % proof stress: 225 N/mm2 Tensile strength: 500-700 N/mm2 Elongation: 40% (for d<=160, longit.) Resistance to interystalline corrosion: yes (in as delivered condition), yes (in sensitised condition) Note: Sensitisation treatment for 15 min at 700oC with subsequent cooling in air. Mechanical Properties At Elevated Temperatures Quenched Condition Temperature 50oC 100oC 150oC 200oC 250oC 300oC 350oC 400oC 0.2 % proof stress in N/mm2 190 176 167 157 147 136 130 124 Forging Hot forming temperature: 1150-850oC. Machinability Excellent speeds and feeds are capable with this material. The addition of sulfur causes a very brittle chip. Many companies now offer premium machinability grades, such as CarTech with their Project 70 and 7000 series. Corrosion Resistance Resistant to a variety of organic and inorganic chemicals, fresh water and atmospheric corrosion. Welding Although not recommended, welding may be performed if low temperatures are employed. Recommended filler metal is AWS E/ER312. At high temperature, the sulfur in 303 tends to precipitate at the weld boundary resulting in weak and brittle joints. Cold working Minor deformation is possible with this alloy, although it is not its strong point. Type 303 Se is superior in this aspect. Forms manufactured: Please see the Dimensional Sales Program.
