Round Steel
Round steel is a basic form of steel. Its core use is as a raw material for mechanical processing and building structural materials. Its specific applications cover multiple fields such as industrial manufacturing, construction, and transportation. Round steel of different materials and processes Applicable to different fields:
Mechanical manufacturing field (core use)
Mechanical parts that require cutting, forging, and welding all use round steel as the initial raw material.
01
Construction and infrastructure
The tensile strength of round steel serves as the "skeleton" or independent load-bearing member of a concrete structure.
02
Special industry-specific scenarios
According to the material properties, round steel is also used in special fields that require corrosion resistance, heat resistance and wear resistance.
03
Other auxiliary uses
Agricultural machinery, daily necessities, art and decoration
04
Chemical and food industries
304 and 316 stainless steel round bars are used to manufacture pipes, valves, and reactors to resist acid and alkali corrosion or meet hygiene standards.
05
Processing shaft parts: Motor shafts, automobile transmission shafts, and machine tool spindles often use 45# high-quality carbon steel or 40Cr alloy round steel to ensure strength and toughness.
Manufacturing transmission components: Gears, sprockets, and couplings are mostly made of alloy round steel such as 20CrMnTi (carburizing steel) or SCM415 (chrome-molybdenum steel), and their surface hardness is improved through heat treatment.
Steel structure support: The steel columns and scaffolding poles of the factory are made of Q355 alloy round steel, which has stronger bending resistance than ordinary carbon steel and is suitable for heavy-load scenarios.
High temperature environment applications: The furnace tube supports of boilers and kilns are made of Cr25Ni20 heat-resistant steel round bars, which can maintain strength at high temperatures above 1000℃.
Tool and mold making: T10A high carbon round steel or high speed steel round steel is used to process cutting tools, dies and measuring tools, relying on its high hardness and wear resistance.
Round Steel are made from various materials, each offering unique properties suited to different applications:
1. Carbon structural steel (the most basic and the largest amount)
●Representative grades: Q235, 10#, 20#, and 45#.
●Core Features: Q235 emphasizes room-temperature strength and is primarily used in construction and support structures; 10# and 20# steels exhibit excellent plasticity and are suitable for forging and welding; 45# steel is a representative medium-carbon steel and can be hardened through heat treatment (quenching and tempering), achieving a balance between strength and toughness.
●Typical Applications: Steel structural columns, bolts and nuts, general shafts, and mechanical components.
2. Alloy structural steel (high strength and high toughness requirements)
●Representative grades: 40Cr, 20CrMnTi, 35CrMo, and SCM415 (Japanese standard, equivalent to 15CrMo in China).
●Key Features: 40Cr is a "versatile alloy steel" with excellent comprehensive mechanical properties; 20CrMnTi is suitable for carburizing, resulting in a hard surface and tough core; 35CrMo is resistant to high temperatures and creep, making it suitable for high-temperature and high-pressure applications.
●Typical Applications: Automotive transmission gears, engine crankshafts, construction machinery shafts, and high-voltage equipment parts.
3. Stainless steel (corrosion resistance, high appearance requirements)
●Representative grades: 304, 316, 410, and 201.
●Key Features: 304 offers the greatest versatility and resistance to room-temperature freshwater and air corrosion. 316, due to its molybdenum content, offers superior resistance to acid, alkali, and seawater corrosion. 410 is a martensitic stainless steel that can be heat-hardened, offering a balance of strength and corrosion resistance. 201 offers lower cost, but its corrosion resistance is slightly inferior to 304.
●Typical Applications: Food processing machinery, medical equipment, chemical piping, decorative ornaments, and components for coastal environments.
