Rebar (reinforcing bar) and HR Coil (Hot Rolled Coil) are two distinct types of steel products, used for different purposes, and their chemical compositions are tailored for their respective applications. Here's a comparison of their typical chemical compositions: 1. Rebar (Reinforcing Bar) Rebar is primarily used in reinforced concrete structures to improve their tensile strength. The chemical composition is designed for ductility, corrosion resistance, and strength. Typical chemical composition of rebar (in percentage): Carbon (C): 0.25% to 0.30% Manganese (Mn): 0.50% to 1.50% Silicon (Si): 0.15% to 0.30% Sulfur (S): ≤ 0.05% Phosphorus (P): ≤ 0.05% Chromium (Cr): Sometimes added for corrosion resistance, up to 0.20% Nickel (Ni): ≤ 0.50% Copper (Cu): ≤ 0.40% Standards like ASTM A615 and A706 guide the composition of rebar. 2. HR Coil (Hot Rolled Coil) HR coils are used in various applications, including construction, automotive, and manufacturing. The chemical composition is usually designed for formability, weldability, and strength. Typical chemical composition of HR coil (in percentage): Carbon (C): 0.10% to 0.25% Manganese (Mn): 0.30% to 1.50% Silicon (Si): 0.10% to 0.35% Sulfur (S): ≤ 0.04% Phosphorus (P): ≤ 0.04% Aluminum (Al): ≤ 0.03% (acts as a deoxidizer) Nitrogen (N): ≤ 0.01% Standards like ASTM A36 and ASTM A1011 define the specifications for HR coils. Key Differences: Carbon Content: Rebar typically has higher carbon content than HR coil, improving its tensile strength but making it less ductile. Manganese: Both products have manganese, which adds strength and toughness, though the levels can vary slightly. Applications: Rebar is more focused on tensile strength for concrete reinforcement, while HR coils emphasize formability for manufacturing.
Sir Metal Mai Se Silicon Ko Km Kaise Kiya Jaa Sakta Hai Hum Pig Iron Ki Casting Karte Hai But Pig Iron Mai Silicon Jayada Aa Raaha Hai Can We increase with carbon
Slag formation ke jariye ---- chuna pathhar (lime stone) silicon ke sath react karke silicon dioxide banta hai, jo iron se halka hota hai or ye upar slag banke bahar aa jata hai
The screws used in sewing machines are typically made of metal, often stainless steel or another corrosion-resistant alloy. The exact chemical composition can vary depending on the specific type of screw and its intended application. It's common for these screws to contain iron, carbon, chromium, and other trace elements that provide strength, durability, and resistance to wear and tear. If you need more detailed information, it would be best to refer to the specifications provided by the manufacturer of the sewing machine or the screws themselves.
Steel ka checking Mechanical and Chemical main hota hai jisme koi chemical use nahi hota, Non metallic inclusion test and itching test me polish karne ke baad HCL ya fir Aluminium per sulfate use hota hai visibility increase karne ke liye

Aapse bahut kuchh sikhane Ko Mila 🙏
@@DharmendraYadav-f7q2t Thanks
Sir very nice explanation,ap bhut hi simple language. Me samjhaye h ,kuchh log log English ko aise padh kr btade h samajh me nhi ata h
Shukriya 😊
❤ thanks sir very helpful
Most welcome
Sir lab incharge ( Is 1786-2008) ke tahat kavan se document taiyar karte hai jisase o company ko Tmt bar ka licence de pate hai
What is the IS CODE for Chemical composition of mild steel and medium tensile bar... For 32mm dia...
Great sir
Thanks
Sir wire rod 5.5mm ke बारे मे बताये, composition कैसे करे कि wire drawing बेस्ट हो sake
Sir, please give the details of the rebar vs hr coil chemical composition..
Rebar (reinforcing bar) and HR Coil (Hot Rolled Coil) are two distinct types of steel products, used for different purposes, and their chemical compositions are tailored for their respective applications. Here's a comparison of their typical chemical compositions:
1. Rebar (Reinforcing Bar)
Rebar is primarily used in reinforced concrete structures to improve their tensile strength. The chemical composition is designed for ductility, corrosion resistance, and strength.
Typical chemical composition of rebar (in percentage):
Carbon (C): 0.25% to 0.30%
Manganese (Mn): 0.50% to 1.50%
Silicon (Si): 0.15% to 0.30%
Sulfur (S): ≤ 0.05%
Phosphorus (P): ≤ 0.05%
Chromium (Cr): Sometimes added for corrosion resistance, up to 0.20%
Nickel (Ni): ≤ 0.50%
Copper (Cu): ≤ 0.40%
Standards like ASTM A615 and A706 guide the composition of rebar.
2. HR Coil (Hot Rolled Coil)
HR coils are used in various applications, including construction, automotive, and manufacturing. The chemical composition is usually designed for formability, weldability, and strength.
Typical chemical composition of HR coil (in percentage):
Carbon (C): 0.10% to 0.25%
Manganese (Mn): 0.30% to 1.50%
Silicon (Si): 0.10% to 0.35%
Sulfur (S): ≤ 0.04%
Phosphorus (P): ≤ 0.04%
Aluminum (Al): ≤ 0.03% (acts as a deoxidizer)
Nitrogen (N): ≤ 0.01%
Standards like ASTM A36 and ASTM A1011 define the specifications for HR coils.
Key Differences:
Carbon Content: Rebar typically has higher carbon content than HR coil, improving its tensile strength but making it less ductile.
Manganese: Both products have manganese, which adds strength and toughness, though the levels can vary slightly.
Applications: Rebar is more focused on tensile strength for concrete reinforcement, while HR coils emphasize formability for manufacturing.

Sir steel check kar ne ka chemical kese Banta hai please recipe milegi

Bhai please do use any company property... it is confidential.
Matlab samjha nahi, Isme sirf TC hi hai jo net par easy available hai, confidential kaise hua
