Understanding Magnetic properties of 304 and 316 stainless steel

It’s important to understand when selecting a grade of stainless steel (SS) for your application or prototype, if the material needs to have magnetic properties or not.  Before determining this, it is good to understand what makes a grade of stainless steel magnetic or not.   Stainless steels are iron-based alloys particularly known for their generally excellent corrosion resistance.  There are several different types of stainless steels.  The two main types are austenitic (MicroGroup items: 304H20RW, 304F10250X010SL for example) and ferritic (automotive applications, kitchenware, and industrial equipment), each contains a different chemical arrangement.  Due to this difference, ferritic stainless steels… Read more »

Choosing the Best Metal Alloy for Your Project

metal alloys

Selecting the optimal metal alloy for a project is a decision that requires in-depth industry knowledge and research. Different types of metal alloys have unique properties that determine the function of a product, material, or the quality of the equipment manufactured. At MicroGroup, we understand that you need to manufacture products that are durable and resilient. So how do you select the ideal metal alloy for your products, and what are the properties of some common alloys? Factors to Consider When Selecting a Metal Alloy In order to choose the best metal alloy, you need to first consider the conditions… Read more »

Welded Vs. Seamless Stainless Steel Tubing – Choosing the Best Product for Your Application

welded tubes

When choosing stainless steel tubing material, a decision you may need to make is whether your project should use seamless or welded and drawn tubing.   For decades, all stainless steel tubes were seamless. However, advances in welding and metal purification technologies have given rise to the popularity of welded tubing.   What Is Seamless Stainless Steel Tubing and What Are the Advantages? Seamless tubing has no longitudinal weld seam. The manufacturing of seamless tubing requires a mechanism to force the hole into the billet.   Rotary piercing and rolling is the most common method for producing seamless tubing today…. Read more »

ASTM Standards – Specifications for Excellence

ASTM Standards

ASTM standards are formal, technical requirements that establish quality specifications for a wide range of materials, products, systems, and services; they serve as the basis for manufacturing, procurement, and regulatory activities worldwide. ASTM stands for American Society for Testing and Materials.   The standards are developed and published by ASTM International, a non-profit organization that utilizes technical committees to establish voluntary standards by means of committee consensus. They provide specifications for steel, plastics, textiles, electronics, testing methods, sports equipment, and thousands more materials and processes.   While there are other standards used in the industry for stainless steel tubing (MIL-T,… Read more »
