SS 301 Full Hard Coil is a high-strength stainless steel coil product, made from grade 301 stainless steel, which has been cold worked to achieve its full hard condition. This form of stainless steel is known for its excellent strength, corrosion resistance, and durability, making it suitable for various industrial applications where both strength and moderate corrosion resistance are required.

• Stainless Steel Grade 301: This is a chromium-nickel austenitic stainless steel. It contains approximately:

  • 16-18% Chromium (Cr): Provides corrosion resistance by forming a passive oxide layer on the steel's surface.
  • 6-8% Nickel (Ni): Enhances the steel's toughness, improves resistance to oxidation, and contributes to its ability to withstand deformation.
  • Up to 0.15% Carbon (C): Increases the strength and hardness of the steel, especially when cold worked.

• Work-Hardened: The "full hard" condition refers to the material being heavily cold worked, which drastically increases its tensile and yield strength while reducing its ductility. This work-hardening process makes SS 301 Full Hard one of the strongest forms of austenitic stainless steel.

• Magnetic Properties: When cold worked, SS 301 becomes magnetic due to the transformation of some of the austenitic structure into martensite, especially in its full hard condition.

• Corrosion Resistance: Although SS 301 has moderate corrosion resistance, it is not as corrosion-resistant as other austenitic stainless steel grades like 304 or 316. It performs well in mild corrosive environments but is not suitable for harsh or marine environments.

• Tensile Strength: In the full hard condition, SS 301 has a tensile strength of approximately 185,000 PSI. This makes it suitable for high-stress applications where material strength is crucial.

• Yield Strength: The yield strength of SS 301 Full Hard can reach around 140,000 PSI, allowing it to resist deformation under high loads.

• Hardness: The hardness of SS 301 in the full hard condition is typically measured at Rockwell C40, indicating significant hardness and wear resistance.

• Ductility: In the full hard state, the material has low ductility and is less formable. It can still be bent or stamped but requires more force and precision to avoid cracking.

• Cold Rolling: SS 301 Full Hard Coil is produced through a cold rolling process, where the steel is rolled at room temperature after the initial hot rolling. Cold rolling increases the steel’s strength and hardness through plastic deformation.

• Annealing and Tempering (Optional): Although full hard SS 301 is often used without annealing, certain applications may call for controlled heat treatment to fine-tune its mechanical properties.

• Springs: One of the most common uses of SS 301 Full Hard Coil is in the production of springs, including flat, coil, and leaf springs. The material’s high tensile strength allows springs to handle significant loads and repeated stress without permanent deformation.

• Clips and Fasteners: Its strength and moderate corrosion resistance make SS 301 full hard ideal for making fasteners, clips, and other hardware that need to maintain their structural integrity under high stress and moderate corrosion conditions.

SS 301 Full Hard Coil is a versatile stainless steel product that is heavily cold-worked to achieve its maximum hardness. The "301" refers to the specific stainless steel grade, which is part of the austenitic family of stainless steels. Austenitic stainless steels are known for their good corrosion resistance and high mechanical strength due to their high chromium and nickel content, along with their ability to be work-hardened through cold rolling.

• Chromium (16-18%): This element is crucial for providing corrosion resistance. It forms a passive oxide layer on the surface of the metal, which protects it from oxidation and corrosion.
• Nickel (6-8%): Nickel enhances corrosion resistance and improves the toughness of the steel, particularly at lower temperatures. It also contributes to the overall formability of the alloy.
• Carbon (up to 0.15%): Carbon increases the hardness and strength of the material, especially when cold worked, but it slightly reduces the material’s corrosion resistance.

• High Strength: In the full hard condition, SS 301 has undergone extensive cold working, resulting in a very high tensile strength that can exceed 185,000 PSI. This makes it one of the strongest forms of austenitic stainless steel.
• Work-Hardening Capacity: SS 301 has a high work-hardening rate, which means that it can be strengthened through mechanical deformation, such as rolling or bending. The material can be supplied in a wide range of temper conditions from annealed (soft) to full hard, depending on the needs of the application.
• Magnetic Properties: Unlike the fully austenitic stainless steels, SS 301 becomes magnetic when cold worked due to the transformation of its austenitic structure into martensitic phases.
• Moderate Corrosion Resistance: SS 301 provides moderate corrosion resistance, making it suitable for environments where it will encounter mild to moderate corrosion, such as indoor or lightly corrosive outdoor conditions. However, it is less corrosion-resistant than stainless steel grades such as 304 or 316.

1. Automotive: SS 301 Full Hard Coil is widely used in the automotive industry for components like springs, fasteners, and clips that require high strength and good wear resistance. Its high tensile strength helps reduce weight while maintaining durability, a crucial factor in modern automotive design.
2. Aerospace: The aerospace industry demands materials that are both lightweight and strong. SS 301 Full Hard meets this requirement and is commonly used in parts such as brackets, clamps, and other structural components.
3. Industrial Equipment: Many manufacturers of industrial machinery and equipment rely on SS 301 for parts that require high wear resistance and the ability to withstand repeated stress and strain. Examples include conveyor belts, blades, and brackets.
4. Electronics: The strength and moderate corrosion resistance of SS 301 make it suitable for electrical enclosures, connectors, and springs used in a variety of electronic devices.
5. Appliances: Components like handles, structural supports, and clips in home appliances often use SS 301 for its durability and formability.

• Tensile Strength: 185,000 PSI (Full Hard)
• Yield Strength: Typically around 140,000 PSI
• Hardness: Typically measured at Rockwell C40 for full hard conditions
• Elongation: Very low in the full hard condition, typically around 1-2%, as the material has lost much of its ductility during cold working.

SS 316 full hard coil with a thickness of 0.2mm refers to a stainless steel coil made of grade 316 stainless steel that has undergone a full hardening process to achieve maximum strength and hardness.

Stainless steel grade 316 is an austenitic stainless steel alloy that contains molybdenum, which enhances its corrosion resistance, especially in chloride environments. It offers excellent strength, high-temperature resistance, and good weldability.

The term "full hard" indicates that the stainless steel coil has undergone a specific cold-rolling and annealing process to achieve its maximum hardness. This process involves cold rolling the stainless steel strip to reduce its thickness and then subjecting it to an annealing treatment to enhance its mechanical properties.

Applications for SS 316 full hard coils include:

1. Automotive Industry: Full hard stainless steel coils are used in the automotive industry for various components that require high strength and corrosion resistance, such as springs, fasteners, and brackets.
