Product Description

Stainless Steel 431 scrap clean technical specifications and commercial data without element chemical symbols for pressed scrap and loose scrap:

Material Identification

  • Material Grade: Stainless Steel 431 / UNS S43100 / 1.4057

  • Alloy Class: High-Chromium, High-Nickel Martensitic Stainless Steel

  • Magnetic Nature: Strongly Magnetic (in all conditions)

  • Scrap Type: Clean Pressed Bundles / Clean Loose Scrap (free of oil, heavy rust, scale, slag, paint, and foreign attachments)

Chemical Composition Limits (Percent by Weight)

  • Chromium: 15.00 to 17.00

  • Nickel: 1.25 to 2.50

  • Carbon: 0.20 Maximum

  • Manganese: 1.00 Maximum

  • Silicon: 1.00 Maximum

  • Phosphorus: 0.040 Maximum

  • Sulfur: 0.030 Maximum

  • Iron: Balance

Physical Forms and Categories

  • Pressed Scrap (Baled Grade):

    • Hydraulically compressed bales, cubes, or bundles composed of sheet offcuts, trim skeletons, and thin stampings

    • High-density bundles prepared for rapid furnace charging and minimal melt-loss

  • Loose Scrap (Heavy Melt Grade):

    • Solid round, square, and hexagonal bar offcuts

    • Heavy plate cuttings, forging flash, and ingot ends

    • Shaft offcuts, marine hardware scrap, and heavy valve body drop-offs

    • Heavy-wall tube crop ends and thick structural shearings

Physical and Thermal Properties

  • Density: 7.75 grams per cubic centimeter

  • Melting Point Range: 1420 to 1470 degrees Celsius

  • Maximum Continuous Service Temperature: Up to 700 degrees Celsius in air

Quality and Contamination Thresholds

  • Pressed Scrap (Baled):

    • Bundle Density: High compaction (minimum 75 to 100 pounds per cubic foot / 1.2 to 1.6 grams per cubic centimeter)

    • Non-Metallic / Dirt Contamination: Less than 1.0 percent internal trapped debris

    • Moisture & Oil: Dry / Zero free liquids or heavy greases trapped inside bales

  • Loose Scrap:

    • Thickness: 3.0 millimeters (1/8 inch) and heavier preferred for heavy melt additions

    • Non-Metallic Contamination: Less than 0.5 percent

    • Oil and Grease Attachment: Nil / Cleaned surface

    • Foreign Alloy Mixing: Zero allowable high-nickel austenitic grades, carbon steel, free-machining sulfurous grades, or non-ferrous contaminants

Primary Industrial Applications for Remelting

  • High-tensile pump and propeller shafts

  • Aircraft fittings, structural fasteners, and bolt stock

  • Valve components, stems, and hydraulic equipment

  • Industrial equipment operating in marine and mildly corrosive environments
