SX 430 Technical Data
Summary
SX430 is a low-carbon plain chromium ferrite Stainless Steel. The steel has good corrosion resistance in mildly corrosive environments and good resistance to oxidation at elevated temperatures. In the annealed condition the steel is ductile, does not harden excessively during cold work and can be formed using a large variety of roll forming or mild stretch-bending operations, as well as the more common drawing and bending processes. The steel has limited weld ability and should not be used in the as welded condition for dynamic or impact loaded structures. Being a ferritic material, 430 is liable to brittle fracture at sub-zero temperatures, and cannot be used in cryogenic applications. As the steel does not contain nickel or molybdenum, it is cheaper than any of the 300 series steels.
Typical Applications
430 is a simple corrosion and heat-resisting grade and finds application in areas where mildly corrosive conditions occur or where scaling resistance at moderate temperatures is required. Typical applications include: Automotive trim, architectural applications such as industrial roofing and wall cladding, kitchen utensils, sinks, washing machine parts and industrial pipe and tube. Materials handling equipment in the mining and sugar industry. Heat resisting applications up to 759oC.

Welding
430 has adequate weldability for many applications. However it is prone to embrittlement in the weld/haz. The fatigue properties of 430 in the welded condition are poor and it is not recommended for applications where applied tensile or impact loading will be experienced.
Thermal Processing
1. Annealing
Annealed 430 is in the softest and most ductile condition, and may be used for cold-working operations. The annealing temperature range is 760oC followed by cooling in air.
2. Stress relieving
Stress relief after Welding is not usually required, although 200-300oC is the recommended stress relieving temperature range.
3. Hot working
Initial
forging and pressing temperature range: 1100 - 1150oC
Finishing
temperature:
below 750oC
Avoid extended holding times above 1000oC as excessive grain growth takes place, which severally reduces ductility
Note: Soaking times to ensure uniformity of temperature are longer for Stainless Steels than for carbon steels. Use up to 1/2 times the time employed for the same thickness of mild steel.
Cold Working
430 can readily be fabricated by cold working. Typical operations include bending, forming, deep drawing and upsetting.

Principal Design Features
One of the most widely used precipitation hardening grades in the business. While soft and ductile in the solution annealed condition, it is capable of high properties with a single precipitation or aging treatment. Characterized by good corrosion resistance, high harness, toughness and strength.
Machinability
Long, gummy chips characterize this alloys machinability. It can be machined in the annealed condition, however condition H1150M will yield best results. Post machining solution treatment of parts will be required prior to final hardening if machining in this condition.
Heat Treatment
CONDITION A--Soak at 1900 F (1038 C) for 30 minutes and cool below 60 F (16 C) for complete martensite transformation. CONDITION H 950- Treat Condition A material at 900 F(482 C) for 1 hour, air cool.. CONDITION H925, H1025, H1075, H1100, H1150- Soak solution treated material for 4 hours at specified temperature, air cool, CONDITION H1150M- Soak solution treated material at 1400 F (760 C) for 2 hours, air cool, then re-heat to 1150 F (620 C) for 4 hours and air cool.
Welding
Successfully welded by common fusion and resistance methods, this alloy should not be joined by oxyacetylene welding. AWS E/ER630 filler metal is recommended if required.
Forging
Soak for 1 hour at 2150 F (1177 C) prior to forging. Do not work below 1850 F (1010 C). Post-work solution treatment is required prior to final hardening.
