Grade 430 has good resistance to a wide variety of corrosive media including nitric acid and some organic acids. It attains its maximum corrosion resistance when in the highly polished or buffed condition. Its resistance to pitting and crevice corrosion resistance is a little lower than that of Grade 304. It is not usually recommended for Grade 430 to be subjected to exterior exposure, but it performs well in mild indoor environments. Stress corrosion cracking resistance of Grade 430 is very high, as it is for all ferritic grades.
The Chinese brand corresponding to the 430 stainless steel pipe --S43000,AISI, ASTM 430 is 1Cr17. Its characteristics and USES are as follows: general steel with good corrosion resistance, building interior decoration, heavy oil burner parts, household appliances, household electrical parts, excellent deep-drawing performance, similar to 304 steel;
It has strong corrosion resistance to oxidizing acids and corrosion resistance to alkali liquor and most organic acids and inorganic acids.Stress corrosion cracking resistance is stronger than 304 steel;
The thermal expansion coefficient is lower than 304 steel, which has high oxidation resistance and is suitable for heat-resistant equipment.Cold rolling product appearance of good brightness, beautiful
Grade 430 Resists oxidation in intermittent service up to 870°C and to 815°C in continuous service. This grade may become brittle at room temperature after prolonged heating in the 400-600°C range. This effect can be eliminated by annealing.Heat Treatment Solution Annealing Heat to 815-845°C, hold for ½ hour per 25mm of thickness, slow furnace cool to 600°C and then quickly air cool. Slow cooling from 540- 400°C will cause embrittlement.Sub-Critical anneal,Heat to 760-815°C and then air cool or water quench.
These properties for 430 are specified for flat rolled product (plate, sheet and coil) in ASTM A240/A240M. Properties of Grade 430F are specified for bar in ASTM A582. Similar but not necessarily identical properties are specified for other products in their respective specifications.
If welding is necessary pre-heat at 150-200°C. Embrittlement in the weld metal and heat affected zone can be reduced by a post-weld anneal at 790-815°C, but grain refinement will not occur. Use Grade 430, 308L, 309 or 310 filler rod, depending upon application. AS 1554.6 pre-qualifies welding of Grade 430 with Grade 309 filler rods and electrodes.
Grade 430 is easier to machine than the standard austenitic grades such as 304, but there is still a tendency for galling and pick-up on the cutting tool. Bars that have been lightly drawn are easier to machine than those in the annealed condition, but Grade 430 is not usually available in bar. Grade 430F, the free machining version of 430, is very much easier to machine.
