301 Stainless Steel Sheets and Plates Supplier

Composition and Structure:

• 301 stainless steel sheet is an austenitic stainless steel containing moderate amounts of chromium and nickel, and its strength and hardness increase after cold processing.
• 310 stainless steel sheet is a chromium-nickel stainless steel with higher chromium and nickel content, exhibiting excellent corrosion resistance and high-temperature oxidation resistance.

Corrosion Resistance:

• 301 stainless steel sheet may exhibit poor corrosion resistance in certain specific environments, such as acidic or alkaline chemical media.
• 310 stainless steel sheet, due to its higher chromium and nickel content, offers better corrosion resistance, particularly suitable for high-temperature and strong corrosive environments.

High-Temperature Performance:

• Although 301 stainless steel sheet can withstand high temperatures, its high-temperature performance is relatively weaker, typically used below 840°C.
• 310 stainless steel sheet has superior high-temperature performance, capable of withstanding higher temperatures, commonly used for manufacturing components in high-temperature environments.

Composition:

• 301 stainless steel sheet is mainly composed of 18% chromium, 8% nickel, and contains a certain amount of carbon.
• 304 stainless steel sheet contains 18% chromium, 8% nickel, but has a relatively lower carbon content.

Mechanical Properties:

• 301 stainless steel sheet, due to its higher chromium content, lesser nickel content, and moderate amount of carbon, exhibits higher strength and hardness, with excellent work hardening properties (non-magnetic).
• 304 stainless steel sheet, with its lower carbon content, has relatively softer mechanical properties, but its wear resistance and fatigue strength are superior to 301 stainless steel.

Corrosion Resistance:

• 301 stainless steel sheet may exhibit poor corrosion resistance in certain specific environments, such as acidic or alkaline chemical media.
• 304 stainless steel sheet, due to its higher chromium and nickel content, as well as lower carbon content, possesses better corrosion resistance and finds wide applications in equipment and components requiring excellent corrosion resistance.

Composition:

• 301 stainless steel sheet is primarily composed of 17% chromium, 7% nickel, and a moderate amount of carbon.
• 316 stainless steel sheet contains higher levels of chromium (16-18%) and nickel (10-14%), with the addition of 2-3% molybdenum to enhance its corrosion resistance properties.

Corrosion Resistance and High-Temperature Resistance:

• 301 stainless steel sheet may exhibit poor corrosion resistance in certain specific environments, such as acidic or alkaline chemical media, and its high-temperature resistance is relatively weaker.
• 316 stainless steel sheet, due to its high chromium, high nickel content, and the addition of molybdenum, possesses stronger corrosion resistance and high-temperature resistance, particularly showing superior performance in seawater and certain chemical environments.

Mechanical Properties:

• 301 stainless steel sheet exhibits higher strength and hardness, making it easy to increase its strength through cold working, suitable for applications requiring higher hardness and strength.
• 316 stainless steel sheet also has good ductility, toughness, and cold deformation ability, while its strength and corrosion resistance make it perform exceptionally well in various applications.

Processing 301 stainless steel sheets is relatively easy due to its good ductility, toughness, and cold deformation ability. During cold working, 301 stainless steel sheets exhibit a high rate of work hardening, resulting in a significant increase in tensile strength and yield strength with increasing cold working amount, making it easy to shape and process. However, it is important to note that due to the relatively poor corrosion resistance of 301 stainless steel sheets in certain specific environments, it is necessary to avoid using corrosive media such as strong acids and alkalis during the processing.

The three major series of stainless steel are the 200 series, 300 series, and 400 series. Among them, the 300 series is the most commonly used stainless steel series, while the 400 series and 200 series can serve as alternatives to the 300 series within certain ranges. It is worth noting that the 400 series, due to the absence of nickel elements, is technically stainless iron and can therefore be attracted by a magnet.
