Carbon steel and stainless steel two extremely well-liked grades of pipe and helpful materials for industrial pipe fabrications. Each kind of fabric comes with its personal specific sets of pros and cons and likewise each materials has completely different fabrication concerns. Let’s take a look at some of the primary issues.
Carbon Steel vs. Stainless Steel
Since the invention of steel, metalworkers have produced different grades of steel depending on the appliance. This is done by various the amount of carbon. Generally, steel recipes have a weight proportion of carbon in the 0.2% to 2.

To enhance different properties of the bottom iron, mixtures may also embody chromium, manganese, or Tungsten. Varying proportions of those components produce steel with focused values of ductility (the power of a steel to be drawn right into a wire), tensile energy (the ability to be stretched without breaking), and hardness. They will have an effect on and management the thermal and electrical properties of the steel as effectively. The addition of those materials to the iron varieties an alloy. The supplies themselves serve to take care of the crystal lattice structure of the bottom iron atoms.
Carbon steel relies upon mainly on carbon to kind the durable alloy. Carbon steel could comprise different brokers similar to manganese, cobalt, or tungsten, but the proportion of those supplies is just not specified. The following shows the four types of carbon steel:
– Mild / low – include very low percentages of carbon
– Medium – 0.Three to 0.59% carbon by weight
– High – 0.6 to 0.99% carbon
– Ultra excessive – 1.Zero to 2.0% carbon
These alloys can withstand heat remedy successfully. Comparatively, these recipes produce very strong and exhausting grades of steel. However, carbon steel has comparatively inferior ductility specs. It additionally suffers from a standard disadvantage 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 bottom steel. Bridges can display important visible corrosion harm after only a few years of service. Bridge buildings that might have in any other case lasted a hundred years must be repaired or replaced because of corrosion.
Stainless steel is a unique type of steel which doesn’t corrode. It will get this property by using chromium as a special hardening agent. Most forms of stainless steel have a mass proportion of 10.5% to 11.0% chromium. With using 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 unique and interesting. Like carbon steel, stainless steel also reacts to the oxygen in the air to kind an oxide layer. However, relatively than type an iron oxide layer it forms a chromium oxide layer. Iron oxide is a risky molecule which continues to assist within the oxidation course of. In distinction, chromium oxide is inert. It varieties a protective layer that prevents further oxidation.
Pipe Fabrication Factors
Both carbon steel and stainless steel are used to supply parts and structural components for a variety of purposes. When making a choice for a particular software, engineers must consider several factors:
Tensile Strength and Weight – each carbon and stainless steel have a tensile strength and weight which might be comparable. Their use in pipe fabrication depends partly on the method of the fabrication. When a pipe extruded, the ability to take care of specs is determined by the ductility of the fabric, which is comparable for both alloys. Pipe fittings are generally milled, and metalworkers can once more count on similar results between the 2 materials. Often, designers who desire the ductility of steel with a lower weight consider aluminum. Like stainless steel, aluminum doesn’t corrode.
Reactivity – for purposes requiring no reactivity, stainless steel is the clear choice. A noteworthy utility is kitchen pots and pans. Carbon steel (and aluminum) reacts with meals, producing taste adjustments and potential well being hazards. Stainless steel does not trigger these interactions.
Workability – each materials are easy to work in an array of fabrication strategies, together with hardening to create lengthy-lasting elements, machining with out chipping or cracking, and welding to create durable joints.
In summary, fabrication factors between carbon and stainless steel are similar. The resistance to corrosion is the principle distinction between the 2 alloys. STI Group is happy to supply each stainless steel and carbon steel pipe fabrication.
