Chemical Composition Overview

Material composition plays a critical role in corrosion resistance and mechanical performance.

Grade	Carbon (C)	Silicon (Si)	Manganese (Mn)	Phosphorus (P)	Nickel (Ni)	Chromium (Cr)	Molybdenum (Mo)
304	≤0.07	≤1.00	≤2.00	≤0.035	8.00–11.00	17.00–19.00	—
316	≤0.08	≤1.00	≤2.00	≤0.035	11.00–14.00	16.00–18.00	2.00–3.00
316L	≤0.03	≤1.00	≤2.00	≤0.035	12.00–15.00	16.00–18.00	2.00–3.00

The addition of chromium, nickel, and molybdenum helps create a protective passive layer that enhances resistance to corrosion and environmental exposure.

Mechanical Properties

Mechanical performance is essential for equipment structures that experience vibration, loading, and long operating cycles.

Material Grade	Tensile Strength (MPa)	Elongation (%)
