What is S420MC Steel?

As a premier exporter and manufacturer of high-quality structural steel plates, Gangsteel specializes in producing EN 10149-2 compliant materials, including the versatile S420MC steel.

S420MC steelis a high-strength, low-alloy (HSLA) thermomechanically rolled cold-forming steel with 420 MPa minimum yield strength.

It is designed for cold forming applications such as automotive components, machinery parts, agricultural equipment, and light structural elements where high strength, good formability, and lightweight design are required.

Our S420MC steel sheets and plates are delivered in thermomechanically rolled (+M) condition to ensure fine-grain microstructure, excellent bendability, and consistent properties.

S420MC Steel Overview (EN 10149-2)

S420MC steel(material number 1.0980) is defined in EN 10149-2:2013 — Hot rolled flat products made of high yield strength steels for cold forming — Part 2: Delivery technical conditions.

Designation Breakdown:

Unlike normalized grades like S420N/S420NL (EN 10025-3), S420MC is optimized for bending and deep drawing with guaranteed formability (r/t ratio ≤ 1.0 for 90° bending).

Gangsteel supplies S420MC steel in thicknesses from 1.5 mm to 16 mm, with CEV ≤ 0.43 for superior weldability.

Chemical Composition of S420MC Steel (Ladle Analysis, Max %)

CEV = C + Mn/6 + (Cr+Mo+V)/5 + (Ni+Cu)/15Nb + Ti + V ≤ 0.22% = microalloying for grain refinement and strength.

S420MC vs Similar Grades

S420MCexcels in formability (bend radius r/t ≤ 1.0), while S420N/NL focus on weldability and toughness.

Summary

S420MC steelis a high-strength thermomechanically rolled cold-forming steel (EN 10149-2) with 420 MPa yield, 480–620 MPa tensile, and excellent bendability (r/t ≤ 1.0). It is the ideal choice for lightweight, formable components in automotive and machinery.

FAQ

What is S420MC steel?

S420MC steelis a high-strength low-alloy cold-forming steel with 420 MPa min yield (≤3 mm), 480–620 MPa tensile, and 19% elongation. It is thermomechanically rolled for superior formability and used in automotive and machinery.

What is the chemical composition of S420MC steel?

Max 0.20% C, 1.80% Mn, 0.025% P, 0.020% S, CEV ≤ 0.43, with Nb+Ti+V ≤ 0.22% for grain refinement and strength.

What are the mechanical properties of S420MC steel?

• Yield: 420 MPa (≤3 mm) → 360 MPa (16–40 mm)
• Tensile: 480–620 MPa (≤16 mm), 470–610 MPa (>16 mm)
• Elongation: 19% (≤8 mm), 18% (>8 mm)
• Bend Radius: r/t ≤ 1.0 (longitudinal) for 90° bend.

How does S420MC differ from S420N/S420NL?

S420MCis thermomechanically rolled for cold forming (EN 10149-2), with focus on bendability. S420N/NL are normalized for welded structures (EN 10025-3), with impact toughness at -20°C/-50°C.

What are the applications of S420MC steel?

Primarily for cold-formed parts: automotive chassis, machinery brackets, agricultural implements, and lightweight construction profiles.
