Welded Steel Chain Specifications.
Today we are talking about welded steel chain. In the following, the specifications of NACM – National Association of Chain Manufacturers (who representing domestic manufacturers of chain since 1933) concerning the wide range of products such as stainless steel chain. How to use the chain? These size and related specifications are applicable to chain in […]
Steel. Some Surface Treatments – PART 2
In the previous article, we discussed some of the most common surface cleaning methods, including degreasing and sandblasting. Today, we will focus on additional treatments used for stainless steel and alloy steels. Acid Pickling Before pickling, the material must be thoroughly cleaned in order to remove any grease, oil, or insoluble residues from the surface. […]
Steel. Some Surface Treatments – PART 1
Hot-processing operations such as forging, rolling, welding, and heat treatment generate surface oxidation on carbon steels, alloy steels, and stainless steels. This oxidation layer, commonly known as “scale” or “mill scale”, must be removed because it can create problems during stamping and drawing operations. The presence of scale may compromise the corrosion resistance of the […]

Alloying Elements. What Are the Effects on Stainless Steels? – PART 1
In this post we will discuss the effect of alloying elements on stainless steels . We make an introductory statement Here the chemical elements that containing carbon %, nickel % and chromium %. The alloying elements and their effect on stainless steel ALUMINIUM: NITROGEN: CALCIUM: CARBON: Other alloying elements CHROMIUM: MANGANESE: Find our […]
Stainless Steel Production: AOD and VOD.
AOD and VOD processes elaborate stainless steels from either of two basic production cycles. They are originate from iron ore and steel scrap respectively. AOD production (Argon-Oxygen-Decarburization) In this process the merger is implemented in conventional furnace. Subsequently, the liquid passes to the converter, within which the steel undergoes the refining chemical analysis through redox […]
Why to Use Stainless Steel Bars With Reinforced Concrete?
The early deterioration of concrete structures has become a strong global issues over the past 30 years. Because the reinforcement corrosion in steel with an estimated cost for repairs more than 550 billion dollars. Why use stainless steel bars for reinforcing steel? What are the structures involved in the aforementioned deterioration? Especially those located in […]
Stainless Steel Melting Processes
The first materials able to withstand the aggressive action of the acids were discovered in 1821, thanks to the mixing and the merger of oxides of iron and chromium. A little bit of history Initially, this alloy contained a percentage of chromium of around 1.5 and high carbon values. Only at the end of the […]
Why Use the Dimensional Tolerances?
The form and the size of a drawn object are considered “ideal2 conditions, which cannot be absolutely precise in real life. Why use the dimensional tolerance? Manufacturing processes always have geometric or dimensional erros; in the drawing, it is necessary to indicate the maximum permitted variability (known as tolerances) within which the produced parts are […]
