Product Description
Grade 45# Q355 Mild Steel Coils For Mechanical Parts High Strength Structural Components
Product Overview
Middle Carbon Steel Grade 45# and Q355 are engineered for mechanical parts and high-strength structural components, offering superior performance in demanding industrial applications.
45# Steel Specifications
Core Applications: Primarily used in manufacturing mechanical parts that withstand moderate loads and require strength and toughness, often requiring final heat treatment.
Primary Applications:
- Shafts: Various drive shafts, machine tool spindles, gear shafts, splined shafts
- Gears and Worms: Automotive transmission gears, machine tool gears (for low-impact applications)
- Connecting Rods and Bolts: Engine connecting rods, high-strength bolts
- Molds and Tools: Mold frames for plastic molds, simple stamping dies, hand tools
- Other Structural Components: Rollers, sleeves, pins
Summary: 45 steel is specialized "machinery parts steel" designed for core moving components within machines.
Q355 Steel Specifications
Key Features:
- Chemical Composition: Low carbon (C≤0.24%) with trace alloying elements (Mn, Si, Nb, V), enhanced through solid solution strengthening and grain refinement
- Properties: High yield strength, excellent plasticity and toughness, superior low-temperature impact toughness, and excellent weldability
- Delivery Condition: Typically delivered in hot-rolled or normalized condition for direct welding and use
Main Product Forms:
Steel Coils/Plates: Hot-rolled coils (Q355B), medium-thick plates (Q355C/D/E)
Sections and Profiles: H-beams, I-beams, angle steel, channel steel, steel pipes
Strips and Bars: Corresponding specialized products
Core Applications: Engineering structures requiring excellent weldability, plasticity, and low-temperature toughness
- Building Steel Structures: Main load-bearing structures for high-rise buildings, factories, stadiums
- Bridge Engineering: Highway and railway bridge steel structures
- Construction Machinery: Cranes, excavators, mining equipment, concrete pump trucks
- Vehicles and Ships: Truck beams, dump truck bodies, ship superstructures, pressure vessels
- Power Transmission Towers and Structures
Summary: Q355 is "engineering structural steel" ideal for the skeleton and shell of large buildings, bridges, and equipment.
