What is 304 Stainless Steel Plate

304 stainless steel plate is an austenitic stainless steel sheet containing 18%-20% chromium and 8%-10.5% nickel, complying with international standards such as ASTM A240. It is one of the most widely used stainless steel materials in industrial fields. Its core advantages include excellent corrosion resistance (resisting corrosion from atmosphere, fresh water, and neutral salt solutions), good high-temperature resistance (continuous service temperature up to 870℃), and outstanding formability, allowing processing through stamping, welding, bending, and other processes. It also possesses high toughness and strength with no magnetism. Widely applied in chemical equipment, food machinery, architectural decoration, medical devices, shipbuilding, etc., it is a versatile stainless steel plate balancing performance and cost-effectiveness.

304 Stainless Steel Plate Properties

Excellent Corrosion Resistance

As a core type of austenitic stainless steel, its alloy composition (18%-20% chromium and 8%-10.5% nickel) forms a dense passive film. It can resist corrosion from the atmosphere, fresh water, neutral salt solutions and weak acid/alkali media, and is stable to most organic compounds at room temperature.

Balanced Mechanical Properties

At room temperature, the tensile strength reaches 515-720MPa, yield strength ≥205MPa, elongation ≥40%, combining high toughness and structural stability. It is non-magnetic under normal conditions (weak magnetism after cold working can be eliminated by annealing), capable of withstanding impacts, vibrations and other working conditions, meeting the mechanical requirements of industrial structural components.

High-Efficiency Processing Formability

Compatible with mainstream processing technologies such as stamping, bending, welding (argon arc welding, arc welding, etc.), cutting and polishing. It features high dimensional accuracy and small deformation after forming, with strong adaptability to surface treatments (2B, mirror finish, brushed finish), enabling rapid production of complex structural parts and customized products.

Broad-Spectrum Versatility

Integrating hygienic safety and multi-scenario adaptability, the non-toxic and odorless material complies with food-contact metal material standards, suitable for food machinery and medical devices. Meanwhile, it is high-temperature resistant (continuous service temperature ≤870℃) and oxidation-resistant, balancing decorativeness and practicality. It covers chemical engineering, architecture, shipbuilding, electronics and other industries, serving as a versatile plate that balances cost-effectiveness and application scope.

Frequently Asked Questions

Which is better, 304 or 316 stainless steel?

There is no absolute superiority or inferiority between 304 and 316 stainless steel—selection depends on application scenarios (compliant with industry expertise). The core difference lies in their compositions: 316 contains 2%-3% molybdenum and a higher nickel content, offering significantly better corrosion resistance (especially in high-chlorine, acid-alkali, and seawater environments) and superior high-temperature resistance compared to 304.

304 is cost-effective, suitable for conventional scenarios like atmosphere, fresh water, and general chemical applications. 316 is ideal for harsh environments such as shipbuilding, marine engineering, medical equipment, and strong acid-alkali working conditions but is 20%-30% more expensive than 304. For non-corrosive environments, 304 is an economical choice; for high-chlorine or corrosive media, 316’s corrosion resistance advantage is more prominent.

Is 304 the same as A2?

304 and A2 are not entirely identical, but their core properties and application scenarios are highly consistent (compliant with industry expertise). A2 is a group designation for austenitic stainless steel in the ISO standard (corresponding to ISO 3506), defining a chemical composition range of 17%-19% chromium and 8%-12% nickel. 304 (AISI/UNS S30400) is the most representative specific grade in this group, with its composition and mechanical properties fully meeting A2’s requirements.

In practical applications, A2 is often used as a material grade identifier for fasteners (such as bolts), and its core material is mostly 304 stainless steel. However, the A2 group does not only include 304 but also a few derivative grades with similar properties (e.g., some specifications of 304L). The two can be used equivalently in the industry, but it is necessary to pay attention to standard compatibility (A2 corresponds to ISO, while 304 corresponds to American/Chinese standards). Specific standard requirements should be clarified during procurement.

How much is 304 stainless steel per kg?

As of Dec 31, 2025, the mainstream price of 304 stainless steel (AISI S30400/GB 06Cr19Ni10) is $1.73–$1.91 per kg (FOB China, 13% VAT included), with variations by specification and surface finish :

Cold-rolled 2B sheet: $1.87–$1.91/kg
Hot-rolled pickled sheet: $1.73–$1.84/kg
Small-batch purchases (<2 tons): price increases by $0.014–$0.029/kg

Key price drivers: nickel price (accounts for ~50% of production cost), thickness, surface treatment, and order quantity . Thin gauge (<1mm) costs $0.072–$0.144/kg more than thick plates due to higher processing fees; special finishes (e.g., 8K mirror) are $0.216–$0.288/kg pricier than 2B . This quote complies with GB/T 3280/ASTM A240 standards, reflecting average prices in major Chinese markets .
