Leading Stainless Steel Sheet Suppliers in China

General properties:

• Ferritic, pure chromium, non-hardenable grade 430 offers excellent formability and corrosion resistance along with practical mechanical qualities. Its ability to withstand *** corrosion makes it useful in some chemical applications; however, its primary uses are in appliance parts and automotive trim.
• For use in automatic screw machines, grade 430F is a more machinable variation of this grade that is offered in bar form. Grade 434, which contains molybdenum, shares the same beneficial characteristics as Grade 430, with enhanced corrosion resistance thanks to the added molybdenum.
• ASTM A240/A240M meticulously outlines the premium 430 qualities for flat rolled products, including plates, sheets, and coils. These specifications ensure a high standard of quality. For bars and forgings, while there are similar standards, they may vary slightly. Specifically, ASTM A582 defines the Grade 430F characteristics for bars.

APPLICATIONS:

Typical applications for the versatile 430 grade include:

• Durable linings for dishwashers that withstand daily use.
• Sturdy refrigerator cabinet panels designed for lasting performance.
• Sleek and durable automotive trim.
• Reliable lashing wire for secure fastening.
• Element supports built for durability.
• Stove trim rings that combine functionality with aesthetic appeal.
• High-strength fasteners for various applications.
• Resilient chimney liners for enhanced safety.

Typical applications for the specialized 430F grade include:

• Precision repetition machined components for high-efficiency operations.

SPECIFICATIONS:

• UNS: ASTM/ASTE S43000
• DIN: 1.4016

CORROSION RESISTANCE:

• 430 grade material offers excellent resistance to a broad spectrum of corrosive environments, including nitric and some organic acids. Maximum corrosion resistance is achieved when the surface is highly polished or finely ground. Comparable to grade 304, its pitting and crevice corrosion resistance is substantial. Additionally, like all ferritic grades, 430 stands out for its exceptional resistance to stress corrosion cracking.
• The non-free machining 430F grade, similar to other high sulfur free machining grades, exhibits notably reduced resistance to pitting and crevice corrosion.

HEAT RESISTANCE:

• Grade 430 can resist oxidation up to 870°C in intermittent service and 815°C in continuous service. Extended heating within the 400-600°C range may cause brittleness at room temperature; however, this can be mitigated through annealing.

HEAT TREATMENT:

• Solution Annealing - Heat to 815-845°C, maintaining the temperature for ½ hour per 25mm of thickness, followed by slow furnace cooling to 600°C and rapid air cooling. Slow cooling between 540-400°C can lead to embrittlement.
• Sub-Critical Anneal - Heat to 760-815°C, then air cool or water quench.
• Note that this grade is not hardenable through thermal treatment.

WELDING:

• Pre-heat between 150-200°C is recommended if welding is necessary.
• Post-weld annealing at 790-815°C can relieve embrittlement in the weld metal and heat-affected zone.
• Grain refinement will not occur.

MACHINING:

• Machining is easier compared to standard austenitic grades like 304.
• However, there is still a tendency for galling and material pickup on the cutting tool.
• Bars that have been lightly drawn are easier to machine than those in the annealed condition.
• The 430F grade, a free machining version, offers significantly easier machining.

FABRICATION:

• A lower work hardening rate makes bending and forming easier compared to grade 304.
• However, lower ductility limits very severe operations.
• Severe bends should be made with the bend axis at right angles to the rolling direction.
• Severe cold heading of 430 wire is achievable.
