Stainless steel bars and rods are solid, cylindrical metal products primarily composed of iron, carbon, and a minimum of 10.5% chromium, which provides exceptional corrosion resistance and high strength. They are fundamental components in numerous industrial and commercial applications due to their durability, hygienic properties, and versatility. Key Features and Properties

• Corrosion Resistance: The chromium content forms a passive oxide layer on the surface that self-repairs when damaged, protecting the metal from rust, moisture, chemicals, and harsh environments, including saltwater.
• High Strength and Durability: Stainless steel bars exhibit high tensile strength and toughness, allowing them to withstand heavy loads, stress, and wear without breaking, ensuring a long service life.
• Temperature Resistance: They maintain their strength and structural integrity at both very high and very low temperatures, making them suitable for extreme heat environments like furnaces and power plants.
• Hygiene: The smooth, easy-to-clean surface prevents the buildup of dirt and bacteria, making them ideal for use in the food processing, pharmaceutical, and medical equipment industries.
• Aesthetic Appearance: Available in various finishes (polished, bright, black, etc.), they offer a sleek, high-quality look often used in architectural and decorative applications.
• Formability and Machinability: Depending on the grade and production method (hot rolled or cold drawn), these rods can be easily machined, cut, welded, and formed into specific shapes for precision applications. 

   Common GradesStainless steel bars and rods are available in various grades, each tailored to specific performance requirements: 

• Grade 304: The most common and versatile grade, known for excellent corrosion resistance and formability. Ideal for general-purpose, food processing, and architectural applications.
• Grade 316/316L: Contains molybdenum, offering superior resistance to pitting and crevice corrosion, especially in marine, chemical, and acidic environments.
• Grade 410: A martensitic grade that can be heat-treated to high strength and hardness, suitable for applications like shafts and valve components.
• Grade 17-4PH / Duplex 2205: Precipitation-hardening and duplex grades that offer an exceptional combination of very high strength and superior corrosion resistance for demanding, heavy-duty applications in oil & gas or offshore platforms. 

Typical ApplicationsStainless steel bars and rods are widely used across diverse sectors: 

• Construction: Used as structural components, reinforcement in concrete, and for general fabrication.
• Automotive & Aerospace: Utilized for high-stress parts like shafts, axles, and engine components.
• Industrial Machinery: Essential for gears, fasteners, bearings, rollers, and other machine components.
• Marine Industry: Selected for shipbuilding and offshore platforms due to resistance to saltwater corrosion.
• Medical & Food Processing: Used for equipment, utensils, and medical implants due to their high hygiene standards. 

Products are manufactured to international standards like ASTM A276 and are available from suppliers in various forms, sizes, and finishes.

Stainless steel 420 bar and rod are high-carbon martensitic stainless steel products known for their excellent hardness, strength, and moderate corrosion resistance, especially after heat treatment and polishing. They are available in various forms and finishes for industrial and construction applications. Key Properties and Features

• High Hardness: This grade can achieve high hardness levels (up to 50 HRC) after proper heat treatment, making it suitable for cutting applications.
• Corrosion Resistance: It offers good corrosion resistance in mild environments (freshwater, atmosphere, some acids) when in a hardened and polished condition.
• Magnetic Properties: As a martensitic steel, the 420 grade is magnetic.
• Heat Treatable: The material can be annealed and hardened, providing versatility for different mechanical property requirements.
• Workability: It exhibits good ductility in the annealed condition. 

Available Forms and Finishes Stainless steel 420 bars and rods come in a wide range of forms, sizes, and finishes to suit specific needs: 

• Forms: Round, square, hexagonal, flat, and rectangular bars/rods are commonly available.
• Sizes: Diameters for round bars typically range from 4mm to 500mm, with custom cut lengths available.
• Finishes: Options include bright, polished, black, rough turned, and annealed finishes.
• Manufacturing Technique: The bars are produced using hot rolled, cold drawn, or forged techniques. 

Typical ApplicationsDue to its specific properties, stainless steel 420 is used in various demanding applications: 

• Surgical Equipment: Used in manufacturing instruments due to its ability to be hardened and resist corrosion.
• Cutlery and Knives: The high hardness makes it an ideal choice for cutting tools.
• Shafts and Pumps: Utilized in industrial applications that require durability and wear resistance.
• Construction and Engineering: Used in general assembly, manufacturing units, and structural applications.
• Shear Blades and Needles: Employed in these items where sharp edges and strength are crucial.

• Production Capacity: 500 Ton
• Delivery Time: 1-3 Day Time

The Stainless Steel 410 black bar/rod is a general-purpose, martensitic stainless steel product known for a balance of high strength, hardness, and moderate corrosion resistance, which can be further enhanced through heat treatment. The "black" finish typically refers to a hot-rolled, non-polished surface condition. Key Features and Properties

• Grade & Type: AISI 410 (UNS S41000, WNR 1.4006), a basic hardenable martensitic chromium steel alloy.
• Finish: The "black" finish is a result of hot rolling or forging processes, often supplied in an as-rolled or annealed condition before any further finishing like polishing or grinding.
• Magnetic: It is magnetic due to its martensitic structure.
• Heat Treatment: It responds well to hardening processes (quenching and tempering), allowing for customization of mechanical properties to achieve very high strength and wear resistance.
• Corrosion Resistance: Offers good resistance to atmospheric corrosion, water, and mild acids, but it is less resistant to harsh chemical or marine (chloride) environments compared to austenitic grades like 304 or 316.
• Machinability & Weldability: Moderately machinable, especially in the annealed condition. Welding requires preheating and post-weld heat treatment to prevent cracking and maintain optimal properties.
• Forms: Available in various forms including round, square, hex, and flat bars/rods. 

  Common ApplicationsThe combination of strength, hardness, and corrosion resistance makes SS 410 suitable for a variety of demanding industrial and manufacturing applications. 

• Fasteners: Used for bolts, screws, and nuts that require strength and some corrosion resistance.
• Turbine Components: Ideal for steam and gas turbine blades and buckets due to its heat resistance and strength.
• Machinery Parts: Utilized in pump shafts, valve components, and general engineering applications.
• Cutlery and Tools: Its ability to be hardened to high levels makes it a common material for knives and other wear-resistant instruments.
• Construction & Petrochemical: Used in structural applications, bridges, and petrochemical refinery equipment where durability is needed.
