Carbon Steel: Properties, Production, Examples and Applications
Carbon steel is an iron-carbon alloy, which contains up to 2.1 wt.% carbon. For carbon steels, there is no minimum specified content of other alloying elements, however, they often contain manganese. The maximum manganese, silicon and copper content should be less than 1.65 wt.%, 0.6 wt.% and 0.6 wt.%, respectively.
Types of carbon steel and their properties
Carbon steel can be classified into three categories according to its carbon content: low-carbon steel (or mild-carbon steel), medium-carbon steel and high-carbon steel [1]. Their carbon content, microstructure and properties compare as follows:

◉ FAQ
Q1:What metal materials do you supply?
A:We supply one-stop full range of metal materials: pure copper & brass, carbon steel, hot-dip galvanized steel, PPGI/PPGL color coated steel, 201/304/316 stainless steel, high temperature alloy, industrial aluminum profiles and various structural profiles. Sheets, coils, tubes, bars are all available for infrastructure, new energy, machinery, chemical and electrical industries.
Q2:Can you customize material grades, thickness and sizes?
A:Customization is available. For stainless steel, copper, aluminum, galvanized & color coated steel, thickness, width and length can be adjusted per ASTM & EN standards. Profiles can be cut to fixed length or custom moulded according to drawings. Special alloy materials can be ordered from steel mills.
Q3:What’s the difference between galvanized steel and color coated PPGI?
A:Galvanized steel only has zinc coating for basic anti-rust with lower cost, suitable for brackets, guardrails and load-bearing structures. PPGI is galvanized base with colored paint layer, anti-rust & decorative, widely used for factory roof/wall panels and equipment housings. Thick galvanized steel for rainy coastal areas, PPGI for decorative outdoor projects.
Q4:Do you have spot inventory? What’s your MOQ?
A:We own 10,000 tons standardized warehouse with spot carbon steel, stainless steel, galvanized, copper and aluminum materials. MOQ is 1 ton for standard sizes; small samples of dozens of kilograms are acceptable. No upper limit for bulk engineering orders, mixed container loading with multiple metals is supported.
Q5:How long is the delivery time for spot goods & customized goods?
A:Spot goods can be loaded within 3-7 days; simple cutting processing orders take 7-10 days; mould opening & special alloy customization takes 15-30 days, subject to specific specifications.
