431 stainless steel plate price Per kg
The current 431 stainless steel plate price ranges from USD $4.5–$6.0 per kg, depending on thickness, surface finish, and quantity. Due to global demand and limited stock availability, early procurement is recommended to secure competitive pricing. Bulk orders over 5 tons may qualify for special discounts.
All materials conform to ASTM, JIS, and EN standards and have undergone hardness (HRC 40–50), tensile strength (≥900 MPa), and corrosion resistance testing. We also offer cutting services, CNC machining, moisture-proof packaging, and fast delivery within 7–12 days, ensuring a stable supply for industrial customers such as pump shafts, valves, marine components, and machine parts.
