STAINLESS STEEL 303 / S30300/ 1.4305
AISI 303 (SUS 303) Grade Stainless Steel
Stainless steel type 1.4305 is popularly known as grade 303 stainless steel. Grade 303 is the most readily machineable of all the austenitic grades of stainless steel. The machineable nature of grade 303 is due to the presence of Sulphur in the steel composition. Whilst the Sulphur improves machining, it also causes a decrease in the corrosion resistance and a slight lowering of the toughness. Alloy 409 is available as round / flat / sheet /hexagonal plate/ square /coil / pipe & fittings. The corrosion resistance of type 303 is lower than that for 304. The toughness is still excellent as with other austenitic grades. Property data given in this document is typical for bar products covered by ASTM A582. ASTM, EN or other standards may cover products sold by Tecni-Cable Ltd. It is reasonable to expect specifications in these standards to be similar but not necessarily identical to those given in this datasheet.

STAINLESS STEEL 309 / 1.4829 / X15CRNISI20-12
Designations
Principal Design Features
This alloy is known for good strength and oxidation resistance in continuous service temperatures up to 2000 F (1093 C).It is superior to 304 stainless in both strength and corrosion resistance.
Applications
Oven linings, boiler baffles, fire box sheets, furnace components and other high temperature containers.
Machinability
This alloy machines similarly to type 304 stainless. Its chips are stringy and it will work harden rapidly. It is necessary to keep the tool cutting at all times and use chip breakers.
Welding
Most of the austenitic stainless steels can be readily welded using fusion or resistance methods. Oxyacetylene welding is not recommended. Filler metal should be AWS E/ER 309 or 309L.
Hot Working
Working temperatures are 2150 F (1177 C), with reheating necessary at 1800 F (982 C).Rapid quenching is recommended. Full post-work annealing is required to reattain maximum corrosion resistance.
Cold Working
Although this alloy has a high work hardening rate, it can be drawn, headed, upset, and stamped. Full annealing is required after cold work to remove internal stress.
Availability :
Alloy 309 is available as round / flat / sheet / hexagonal / plate/ square / coil / pipe & fittings.

It resists oxidation in continuous service at temperatures up to 1150°C provided reducing sulphur gases are not present. It is also used for intermittent service at temperatures up to 1040°C Grade 310S (UNS S31008) is used when the application environment involves moist corrodents in a temperature range lower than that which is normally considered "high temperature" service. The lower carbon content of 310S does reduce its high temperature strength compared to 310. |

Stainless steel AISI 317L has as its main characteristic the great addition of molybdenum to its chemical composition, which guarantees an increased resistance to chemical attack when compared with chromium-nicke-molybdenuml austenitic steels of the type AISI 316L. This grade has approximately 1% more chromium, nickel and molybdenum when compared with austenitic steel AISI 316L. Grade AISI 317L offers even better creep deformation characteristics and mechanical resistance to high temperatures when compared with conventional stainless steels. The American denomination “low carbon”, or simply “L”, of grade AISI 317L ensures resistance to sensitization during welding or when thermal processes are applied due to the low carbon in its chemical composition. The combination of molybdenum and nitrogen in the chemical composition of this grade is particularly effective in incresing the resistance to pitting corrosion and crevice, especialy in acid medium with chlorides and sulfur compounds at high temperatures. In addition, nitrogen also contributes to increasing the mechanical strength of the alloy. The main applications of AISI 317L are dedicated to the chemical industry, petroleum and petrochemical industries, industries producing paper and pulp, and as condenseres in power stations using fossile and nuclear fuels. It is intended where it is required to have corrosion resistance to strong organic acids, such as the naphthenic acids found in the petroleum refining.
