Lecong Stainless Manufacturer and Suppliers in Da Nang, Vietnam, provides AWS Class ER420 MIG and TIG filler wire and rod, designed for welding martensitic stainless steels that require higher strength and hardness. This filler metal is often used in applications exposed to abrasion, wear, and moderate corrosion. With stable arc characteristics, excellent feeding, and good bead appearance, ER420 ensures consistent welding performance. Post-weld heat treatment is recommended to improve ductility and corrosion resistance. Lecong Stainless supplies ER420 filler wire and rod to industries in Vietnam and worldwide, offering reliable welding solutions for important structural and industrial tasks.
ER420 typically contains 12–14% chromium and up to 0.3% carbon. This composition leads to high-strength, hard martensitic weld deposits. Mechanical properties feature tensile strength of about 105,000 psi, yield strength near 80,000 psi, and an elongation of 18–20%. Welds are hardenable and should undergo post-weld heat treatment to enhance toughness and corrosion resistance. ER420 offers moderate protection against corrosion while providing excellent abrasion and wear resistance, making it ideal for MIG and TIG welding processes that need high mechanical strength.
