SAIL (Steel Authority of India Limited) HR (Hot Rolled) Coils are steel coils that have undergone the hot rolling process, which involves heating the steel slab above its recrystallization temperature and then passing it through a series of rollers to achieve the desired thickness and shape.

HR coils produced by SAIL are made from high-quality carbon steel and are widely used in various industries such as construction, automotive, fabrication, and manufacturing. They offer excellent strength, formability, and weldability, making them suitable for a wide range of applications.

Here are some key features and specifications of SAIL HR Coils:

1. Size and Thickness:

   • HR coils are available in various sizes and thicknesses, ranging from 1.6 mm to 20 mm or more.
   • The width of HR coils can vary, typically ranging from 900 mm to 2100 mm or more.

2. Standards and Grades:

   • SAIL HR coils comply with various national and international standards such as IS (Indian Standards), ASTM (American Society for Testing and Materials), and others.
   • They are available in different grades, such as IS 1079, IS 2062, ASTM A36, and others, depending on the specific requirements and applications.

3. Surface Finish:

   • SAIL HR coils have a scale or mill scale layer on their surface, which is a dark, rough, and protective oxide layer formed during the hot rolling process.
   • The surface can be further processed or treated, such as pickling or oiling, depending on the intended use.

4. Application:

   • SAIL HR coils find extensive usage in various applications, including construction of structural components, manufacturing of pipes, automotive parts, machinery, and general fabrication.

Hot work tool steel is a type of tool steel specifically designed for high-temperature applications, such as hot forging, extrusion, and die casting. It exhibits excellent thermal stability, strength, and resistance to thermal fatigue, making it suitable for withstanding the intense heat and mechanical stresses encountered in hot working processes. Here are some key aspects of hot work tool steel:

Sizes: Hot work tool steel is available in various sizes and shapes, including rounds, flat bars, and squares. The sizes can vary depending on the specific application and requirements.

Grades: There are several grades of hot work tool steel, each with its unique properties and applications. Some common grades include:

• H13 (AISI): H13 is a widely used hot work tool steel with excellent toughness, heat resistance, and wear resistance. It is suitable for a wide range of hot working applications, such as die casting, extrusion, and hot forging.

• H11 (AISI): H11 is another popular hot work tool steel known for its high-temperature strength and excellent resistance to thermal fatigue. It is often used in hot forging and extrusion dies.

• H21 (AISI): H21 is a chromium-tungsten hot work tool steel with good high-temperature strength and wear resistance. It is suitable for hot working applications that involve high-temperature wear and impact.

• H10 (AISI): H10 is a versatile hot work tool steel with good heat resistance and toughness. It is commonly used for hot punches, forging dies, and extrusion tools.

Applications: Hot work tool steel is commonly used in various high-temperature applications, including:

• Die casting: Hot work tool steel is used for manufacturing dies for the production of metal components through die casting processes.

• Hot forging: It is used to make dies and tooling for shaping and forming metal parts through hot forging processes.

• Extrusion: Hot work tool steel is used to produce dies for extruding materials, such as metal rods and tubes, at high temperatures.

• Hot shearing and cutting: Hot work tool steel is employed in hot shearing and cutting operations, where the material is cut or sheared at elevated temperatures.

Make: Hot work tool steel is manufactured by various steel producers and manufacturers worldwide. Some well-known companies and brands that produce hot work tool steel include Uddeholm, Bohler, ASSAB, Daido Steel, and Carpenter Technology Corporation, among others.

When choosing hot work tool steel, it's crucial to consider the specific requirements of the application, the working temperature, the desired mechanical properties, and the tool's overall performance under high-temperature conditions. Proper heat treatment and maintenance are essential to ensure the longevity and performance of hot work tool steel.
