Carbon steel and stainless steel two extremely widespread grades of pipe and useful materials for industrial pipe fabrications. Each sort of material comes with its own explicit sets of pros and cons and likewise each supplies has completely different fabrication concerns. Let’s take a look at a few of the main concerns.
Carbon Steel vs. Stainless Steel
Since the invention of steel, metalworkers have produced totally different grades of steel relying on the appliance. This is done by varying the quantity of carbon. Generally, steel recipes have a weight proportion of carbon in the 0.2% to 2.1% vary. To enhance other properties of the base iron, mixtures might also embody chromium, manganese, or Tungsten. Varying proportions of these elements produce steel with targeted values of ductility (the power of a metallic to be drawn right into a wire), tensile energy (the power to be stretched with out breaking), and hardness. They will affect and control the thermal and electrical properties of the steel as properly. The addition of these materials to the iron kinds an alloy. The materials themselves serve to maintain the crystal lattice construction of the bottom iron atoms.
Carbon steel relies upon mainly on carbon to kind the durable alloy. Carbon steel may comprise other brokers akin to manganese, cobalt, or tungsten, however the proportion of those materials will not be specified. The next reveals the 4 kinds of carbon steel:
– Mild / low – comprise very low percentages of carbon
– Medium – 0.Three to 0.59% carbon by weight
– High – 0.6 to 0.99% carbon
– Ultra high – 1.Zero to 2.0% carbon
These alloys can withstand heat therapy efficiently. Comparatively, these recipes produce very sturdy and exhausting grades of steel. However, carbon steel has comparatively inferior ductility specs. It additionally suffers from a standard downside of most steel recipes in that it corrodes easily. Corrosion is an oxidation of the steel to a extra stable molecular state that ends in a weakening of the base steel. Bridges can display vital seen corrosion harm after just a few years of service. Bridge structures that may have otherwise lasted 100 years have to be repaired or changed as a consequence of corrosion.
Stainless steel is a novel type of steel which doesn’t corrode.

It will get this property by using chromium as a particular hardening agent. Most forms of stainless steel have a mass proportion of 10.5% to 11.0% chromium. With the use of chromium, stainless steel has the essential properties of steel with the addition of its inability to rust.
The means of corrosion resistance for stainless steel is exclusive and fascinating. Like carbon steel, stainless steel additionally reacts to the oxygen within the air to type an oxide layer. However, rather than kind an iron oxide layer it varieties a chromium oxide layer. Iron oxide is a risky molecule which continues to assist within the oxidation course of. In contrast, chromium oxide is inert. It forms a protecting layer that prevents additional oxidation.
Pipe Fabrication Factors
Both carbon steel and stainless steel are used to provide elements and structural elements for a wide range of purposes. When making a selection for a particular software, engineers must consider a number of factors:
Tensile Strength and Weight – each carbon and stainless steel have a tensile strength and weight that are comparable. Their use in pipe fabrication relies upon partly on the tactic of the fabrication. When a pipe extruded, the flexibility to maintain specs relies on the ductility of the material, which is comparable for each alloys. Pipe fittings are generally milled, and metalworkers can once more expect similar results between the two supplies. Often, designers who want the ductility of steel bar with a lower weight consider aluminum. Like stainless steel tube, aluminum doesn’t corrode.
Reactivity – for applications requiring no reactivity, stainless steel is the clear selection. A noteworthy utility is kitchen pots and pans. Carbon steel (and aluminum) reacts with meals, producing taste adjustments and potential health hazards. Stainless steel does not cause these interactions.
Workability – both materials are straightforward to work in an array of fabrication strategies, including hardening to create lengthy-lasting parts, machining with out chipping or cracking, and welding to create durable joints.
In abstract, fabrication factors between carbon and stainless steel are comparable. The resistance to corrosion is the principle difference between the two alloys. STI Group is pleased to offer both stainless steel and carbon steel pipe fabrication.
