is cast iron the same as ductile iron?

Ductile iron can be bent without breaking, whereas cast iron is brittle and breaks when bent. ... Ductile iron also consists of nodular graphite, which gives it flexibility. Cast iron mainly consists of carbon and silicon. With regard to practical uses, ductile iron pipes are used in sewer and water lines.

Stainless steel pans maintain their heat well, which results in even cooking. The iron in the steel makes them induction-compatible, too. A stainless steel pan cannot be seasoned like a cast iron pan – it'll never be truly non-stick. This makes them unsuitable for certain tasks.

Myth #6: "Modern cast iron is just as good as old cast iron. It's all the same material, after all." ... So long as you've seasoned your pan properly, both vintage and modern cast iron should take on a nice non-stick surface, but your modern cast iron will never be quite as non-stick as the vintage stuff.

Cast iron, an alloy of iron that contains 2 to 4 percent carbon, along with varying amounts of silicon and manganese and traces of impurities such as sulfur and phosphorus. It is made by reducing iron ore in a blast furnace.

Nodular cast iron is made by inoculating the molten metal, just before casting, with a small amount of magnesium or cerium. This causes the free carbon in the finished casting to appear as rounded nodules of graphite, rather than as flakes.

Stainless ('Stains less') has alloying elements added to reduce its tendency to rust or corrode. ... In simple words Iron is an Element while stainless steel is an Alloy which contains Iron, Chromium, Manganese, Silicon, Carbon. In some other forms it may contain significant amount of Nickel and Molybdenum.

Gray iron, or grey cast iron, is a type of cast iron that has a graphitic microstructure. It is named after the gray color of the fracture it forms, which is due to the presence of graphite. It is the most common cast iron and the most widely used cast material based on weight.

It gets harder, and therefore more useful, when it's alloyed, or mixed, with carbon. In fact, carbon composition is the main distinction between cast iron and steel. Cast iron typically contains more than 2 percent carbon, while cast steel often contains between 0.1–0.5 percent carbon.

Ductile iron has low weldability as compared to that of steel. One of the main differences between Ductile Iron Vs Steel is that ductile iron has a carbon content of 3.0%-3.9% and steel has a carbon content of 0.08%-0.60%. ... The steel pipe can in fact be around 35% thinner than the ductile iron pipe.

All steel contains iron, but it also contains carbon. ... The primary difference between iron and steel is that the former is a metal, whereas the latter is an alloy. Iron is simply a metal element that occurs naturally on Earth. In comparison, steel is a man-made alloy that's made by mixing iron and carbon together.

It may be hardened or unhardened, so the term is very generic, usually to differentiate from cast iron. The term is also erroneously used to refer to Ductile Iron or Low Carbon Steel, but it is not the same thing.

Mild Steel Below you can see pictures of both. Black Mild Steel has a dark blue oily surface, and Bright Mild Steel has a silvery grey surface. Because Bright Mild Steel is cold rolled it is accurate in size whereas Black Mild Steel is not as accurate. Mild Steel is reasonably soft and ductile.

The fundamental difference between Cast and wrought aluminum is easy to understand: Cast aluminium is the aluminium that was melted in a furnace and poured into a mold. Wrought aluminium is when the metal is worked in the solid form with the help of specific tools.

Pig iron can also be used to produce gray iron. This is achieved by remelting pig iron, often along with substantial quantities of steel and scrap iron, removing undesirable contaminants, adding alloys, and adjusting the carbon content. Some pig iron grades are suitable for producing ductile iron.

Just like PVC, black malleable iron uses a system of pipe and fittings that fit together with compounds instead of welding. Despite its name, black iron pipe is actually made of a low-grade "mild steel" compound. This gives it much better corrosion resistance than traditional cast iron piping.

Most cast irons have a chemical composition of 2.5–4.0% carbon, 1–3% silicon, and the remainder iron. Grey cast iron has less tensile strength and shock resistance than steel, but its compressive strength is comparable to low- and medium-carbon steel.

Wrought iron is no longer produced on a commercial scale, but is still made for replication, restoration and conservation of historical ironwork. Many products today described as wrought iron are actually made of mild steel.
