Strong, durable, and highly corrosion-resistant, stainless steel stands out from regular steel by maintaining its appearance and properties even in demanding environments. This makes it an ideal choice for industrial, architectural, or manufacturing projects where long-term durability is essential.
Additionally, its non-porous surface prevents bacterial growth and makes it easy to clean and disinfect. This is why stainless steel is widely used in the food industry, hospitals, and laboratories.
At Acier Groupe David, we offer a vast inventory of stainless steel products available in multiple grades and finishes. With our custom processing services and efficient steel delivery logistics, we help you bring your projects to life quickly and accurately.

Understanding Stainless Steel Types, Grades, and Alloys
At Acier Groupe David, we provide a wide range of stainless steel to meet the needs of industrial, food, chemical, marine, and mechanical sectors.
Whether for construction, manufacturing, or machining projects, our stainless steel guarantees performance, durability, and corrosion resistance.
To select the right stainless steel, it’s important to understand the types, grades, alloys, and the codes and numbers that identify them.
Austenitic Stainless Steel – 303, 304, 304L, 309, 310, 316, 316L
The 3xx series corresponds to “austenitic” stainless steels, known for excellent corrosion resistance, formability, and non-magnetic properties.
- 303 – Ideal for machining workshops. The “03” indicates a sulfur-stabilized composition for easier machining.
- 304 / 304L – Industry standard, used for piping, food equipment, and structures exposed to moisture. “04” indicates standard chromium and nickel content (18% Cr / 8% Ni). “L” stands for Low Carbon, making it easier to weld and reducing the risk of intergranular corrosion.
- 309 – High-temperature resistant, perfect for furnaces and industrial applications. The “09” indicates a nickel-enriched alloy for heat resistance.
- 310 – Can withstand extreme temperatures up to 1100°C.
- 316 / 316L – Contains molybdenum for enhanced corrosion resistance in chemical and marine environments. 316L facilitates welding and reduces intergranular corrosion risk.
Ferritic and Martensitic Stainless Steel – 410, 416, 440
The 4xx series includes ferritic and martensitic stainless steels. These are harder, magnetic, and provide excellent mechanical strength, but slightly lower corrosion resistance compared to austenitic steels.
- 410 – Standard ferritic steel, good wear and light corrosion resistance.
- 416 – Machinable version of 410, suitable for precision mechanical components. The “16” indicates composition adjustments to facilitate machining.
- 440 – Very hard, ideal for knife blades and surgical instruments. The “40” indicates a high carbon content for hardness and wear resistance.
Precipitation-Hardening Stainless Steel – 174PH
174PH – “PH” stands for Precipitation Hardening, a heat treatment that increases mechanical strength and corrosion resistance. “174” is the grade number in the PH stainless steel classification.
Duplex Stainless Steel – 2205
2205 – Duplex structure combining ferrite and austenite. “22” indicates chromium content (~22%) and “05” nickel (~5%). This combination provides excellent stress corrosion cracking and pitting resistance, ideal for chemical, petrochemical, and marine industries.
Stainless Steel Finishes and Treatments
Depending on your needs, various treatments and finishes can be applied to optimize durability, appearance, and corrosion resistance:
- Mirror Finish – Very smooth and shiny surface, ideal for food and decorative applications.
- Brushed Finish – Reduces glare, perfect for kitchens, public spaces, and decorative surfaces.
- Passivation – Chemical treatment that strengthens corrosion resistance.
- Electropolishing – Creates an ultra-smooth, hygienic surface resistant to contamination, perfect for pharmaceutical and food industries.
