![]() Effect of strain on microstructure evolution in joint was analyzed by field emission scanning electron microscope (FESEM) and on mechanical properties was also studied. Then pre-strain treatment on 304L welded joint of 9 % was carried out using uniaxial quasi-static tensile at room temperature. SS 303 stainless steel equivalent materials are listed in the datasheet below, including European (German DIN, British BSI, France NF), Japanese JIS and Chinese GB standard (for reference).JIS SUS 304L stainless steel was joined by a combination welding process of plasma arc welding and gas tungsten arc welding (PAW+GTAW). ![]() SS303 material is mainly used for parts that need machining, grinding or polishing, suitable for rapid cutting to make rolls, shafts, bolts, nuts, etc. Nominal speed, cutting rate, and band life for the cutoff band sawing of steel bars Steel being cut Nominal speeds for die cutting of screw threads Work metal Nominal speeds and feeds for thread milling with high-speed steel tools Work material Recommended cutting parameters for indexable drills with uncoated and titanium-coated carbide inserts Material Speed and feed ranges for the spade drilling are listed in the following table. Recommended face angles, along with backoff angles for type 303 stainless steel: Increased tool life attained with coated cutting tools Cutting tool If welding cannot be avoided, AWS E312 filler metal may be considered. Weldingĭue to the high P and S content, SS 303 material is not recommended for welding. Hardening: SS 303 cannot be hardened by heat treatment, but can be hardened by cold working. Recommended annealing temperatures for AISI 303 wrought stainless steel is 1040 ☌ (1900 ☏). ![]() Mechanical Propertiesģ03 steel mechanical properties at room temperature are listed in the following tables. Magnetic: SS 303 is non-magnetic in the annealed condition, but may become slightly magnetic due to cold working. ☏)Ĭoefficient of thermal expansion, 10 -6/K (μin./in.ASTM A314: Standard Specification for Stainless Steel Billets and Bars for ForgingĪISI 303 stainless steel physical properties are given in the following lists, including density, thermal expansion, elastic modulus, thermal conductivity, specific heat capacity and electrical resistance.ģ03 stainless steel density, g/cm3 (lb/in.3).ASTM A473: Standard Specification for Stainless Steel Forgings.ASTM A959: Standard Guide for Specifying Harmonized Standard Grade Compositions for Wrought Stainless Steels. ![]()
