Black pipe is plain steel pipe without any protective coatings. Black pipe is used for a variety of applications around the home. It is very common to see black pipe used for your natural gas line and sprinkler system lines. Since black pipe has no protective coating, it may rust easily in wet or humid environments. To stop the pipe from rusting or corroding on the outside, you should provide a la...

what is alloy steel?An iron-based mixture is considered to be an alloy steel when manganese is greater than 1.65%, silicon over 0.5%, copper above 0.6%, or other minimum quantities of alloying elements such as chromium, nickel, molybdenum, or tungsten are present. An enormous variety of distinct properties can be created for the steel by substituting these elements in the recipe.

How is steel used in buildings?The National Institute of Standards and Technology notes that "steel has become one of the most reliable, most used and most important materials of the age." As an advanced engineered material, steel is the material of choice by engineers and architects because of its strong performance characteristics, reliability, versatility in design, consistency as a product and...

A process for further refinement of stainless steel through reduction of carbon contentThe amount of carbon in stainless steel must be lower than that in carbon steel or lower alloy steel (i.e., steel with alloying element content below 5%). While electric arc furnaces (EAF) are the conventional means of melting and refining stainless steel, AOD is an economical supplement, as operating time is sh...

How steel is used in buildings and infrastructureThe possibilities for using steel in buildings and infrastructure are limitless. The most common applications are listed below.For buildingsStructural sections: these provide a strong, stiff frame for the building and make up 25% of the steel use in buildings.Reinforcing bars: these add tensile strength and stiffness to concrete and make up 44% of s...

There are two ways to anneal cold-rolled steel coils: batch and continuous.Batch (Box) Three to four coils are stacked on top of each other, and a cover is placed on top for up to 3 days, then heated in a non-oxygen atmosphere (to prevent rust) and slowly cooled.Continuous. Normally part of a coating line, the steel is uncoiled and run through a series of vertical loops within a heater. The temper...

A heat or thermal treatment process by which a previously cold-rolled steel coil is made more suitable for forming and bending. The steel sheet is heated to a designated temperature for a sufficient amount of time and then cooled.

what is the corrosion of structural steel?The corrosion of structural steel is an electrochemical process that requires the simultaneous presence of moisture and oxygen. In the absence of either, corrosion does not occur. Essentially, the iron in the steel is oxidised to produce rust, which occupies approximately 6 times the volume of the original material consumed in the process. The general corr...

How does steel fabrication work?All steel components are manufactured in the controlled environment of a fabrication factory, where consistent structural elements with assured quality can be created to meet the specific requirements of each project. In this environment, steel parts can be easily standardised, tested and certified. Any waste material produced during the fabrication phase, e.g. off-...
