430 stainless steel melting point

430 Stainless Steel Melting Point

Gangsteel produces 430 stainless steel in full compliance with the leading international standards. We can manufacture to any of the following major specifications to meet your exact project requirements:

• JIS G4305 SUS430(Japan)
• ASTM A240 Type 430(USA)
• EN 10088-2 1.4016 / X6Cr17(Europe)
• DIN EN 1.4016(Germany)
• GB/T 3280 10Cr17 / 1Cr17(China)
• BS 1449 430S17(United Kingdom)
• ISO 4954 X6Cr17(International)

Melting Point of 430 Stainless Steel

430 stainless steel (AISI 430 / UNS S43000) is a ferritic alloy and does not have a single sharp melting point like pure metals. Instead, it has a melting range (solidus to liquidus):

Melting Range:1425 °C – 1510 °C (2600 °F – 2750 °F)

• Solidus(begins to melt): ≈ 1425 °C (2600 °F)
• Liquidus(fully molten): ≈ 1510 °C (2750 °F)

This range is consistent across all major standards (ASTM A240, JIS G4305, EN 10088-2, GB/T 3280, etc.).

Why the Melting Range Matters

• Allows safe service temperatures up to 815 °C (intermittent) and 760 °C (continuous) without melting or significant scaling.
• Excellent oxidation resistance within the working temperature range.
• Lower melting range than austenitic grades (e.g., 304 melts at 1400–1450 °C), but still suitable for most heat-resistant applications.
