Quality Control for Steel Manufacturing - Socrates Vasiliades
Socrates Vasiliades is an executive chairman at Avima Iron ore limited who is running a business of core mining with many years of experience.
Quality is more important than quantity as it is one of the main things that determine the success of the businesses. When it comes to launching a product, it has to go through some amount of quality checks, before making its launch into the market, which ensures it’s fitness to sale and readiness to consume. It is no doubt that one of the most important industries which may stand for anything but weakness or poor quality has a certain amount of quality parameters or quality control which decides the strength of the metal. It is indeed, the steel which is the epitome and metaphor of strength. Hence, the right quality control is a must to ensure the strength of the metal besides maintaining its metallic properties. In a bid to ensure quality control industry leaders such as Socrates Vasiliades and others are playing their part by spreading awareness among users over various platforms.
To check the quality of the finished products various tests gets conducted. These tests may be broadly classified into two main types. These are either destructive or non-destructive. All the important tests such as metallurgical, fatigue, ductility, compression, tension, hardenability, and hardness fall under either of the two aforementioned types.
Metallurgical testing as the name suggests determines the quality of the steel by analyzing the microstructure of its sample under a fine quality microscope. A cross-section of the sample gets well-polished and then scrutinized under magnification from 100-500 diameters. The microstructure is composed of grains of different sizes. A sample of steel having fine grains is considered better than one with large grains. These fine grains ensure the strength and toughness of the metal. As per the industry leaders such as Vasiliades alloy steels end up having some of the characteristics of both the metals e.g. stainless steel which is considered strong and tough besides having resistance for stain.
Hardness is related to the elastic and plastic properties of the steel. The elasticity of a material is its ability to retain its shape after letting it free stretching. The hardness test procedures are very easy to conduct. The results can further be used to have an idea of some mechanical properties as well. One of the most popular tests includes Rockwell and Brinell used extensively for inspection.
After the hardness test, the tension of the metal gets checked. The tensile test is used to check the mechanical properties of the material. The test is used to determine yield strength and breaking strength. It is important to note that the yield strength of the material is the maximum stress, which a metal can bear, along its axis before it starts changing its shape.
The other important set of tests includes fatigue tests. The word fatigue gives the idea of the weakening of the metal by repeated variations of stress. It determines the effects of corrosion, surface conditions, size, temperature, etc.
Conclusion: Quality has an important role to play to generate higher revenue because high quality increases customer satisfaction which further increases the sales. Like in any other business, quality does have an important role to play in the Steel Industry as steel may stand for anything but weakness. It is used as a metaphor for strength. There are many quality checks that every sample must go through before letting it enter into the market. Some of these tests include metallurgical testing, fatigue tests, hardness tests, hardenability, etc. These tests must be done to make sure the quality of the steel as advocated by Socrates Vasiliades.
