Hardness Testing on Stainless Steel Pipe

Testing and determining the hardness average value of the pipe wall
One aspect of hardness testing is the testing and determination of the hardness average value of the pipe wall after manufacture. Pipes are manufactured using a wide variety of methods, among them rolling processes. Since rolling is a thermo-mechanical process with which mechanical characteristics, along with the pipe wall thickness and diameter of the pipes, can be tested, hardness testing is used for fast determination of mechanical-technological properties.

Determining the grain structure of metallographic constituents with hardness tests
Another aspect of hardness testing is the determination of the grain structure by performing hardness tests on metallographic constituents. Due to the small size of the microstructural components, hardness testers with small to very small forces are used—usually stationary microhardness testers with indentation sizes and depths that can be adapted to the dimensions of the microstructural components via the indentation forces.

Common Stainless Steel Pipes and Their Characteristics and Usee

Steel grade	Grade	Characteristics and Uses
100 Series	101	Commonly used stainless steel grades and their characteristics
100 Series	102	General austenitic stainless steel for furniture applications
200 Series	201	Cold-work-hardening austenitic stainless steel
200 Series	202	Common Austenitic Stainless Steel
300 Series	301	High ductility, suitable for products that need to be formed. It can be rapidly hardened during mechanical processing. It has good weldability. Its wear resistance and fatigue strength are superior to 304.
	302	The corrosion resistance is the same as that of 304. However, due to the additional carbon content, its strength is slightly better.
	303	The semi-machinable type 304 steel containing sulfur and phosphorus, with GB designation of Y12Cr18Ni9, is also referred to as A1 in ISO 3506.
	304	The most commonly used traditional 18/8 stainless steel is GB grade 06Cr19Ni10, also known as A2 in ISO 3506. 304L is similar to 304, but it has reduced the content of C to enhance weldability, and its strength is slightly lower than that of 304. 304LN is similar to 304L, but it has added N to achieve higher yield strength and tensile strength than 304L.
	308	When welding 304, use filler metal as the filler material.
	309	It has better temperature resistance than 304. When welding different steel grades, it is sometimes used together with chromium-nickel-iron alloy as filler metal.
	316	It is an improved type of 304, and it is the second most widely used steel grade after 304, which is for food and medical purposes. It contains the element Molybdenum (Mo), and has a higher Ni content. This makes its corrosion resistance and high-temperature strength significantly enhanced, and its high-temperature resistance can reach 1200 - 1300℃. It can prevent point corrosion, crevice corrosion, corrosion in chloride ion environments, seawater and other special forms of corrosion. Therefore, it can be used under harsh conditions.
	321	Similar to 304, the addition of Ti reduces the risk of weld rusting. To resist sensitization during welding, Nb is added to 347.

Q: Can you provide us sample?

A: Yes, we can. It's free of charge, but the buyer needs to cover the shipping cost.

Q: What is the surface finish of stainless steel pipe?

A: Surface finish is the visual appearance of the metal and is created through various processing methods, including rolling, polishing, and blasting. These finishes range from dull to bright and include special textures that May be mechanically applied for highly specialized applications.

Q: What is the surface treatment of stainless steel pipe?

A: Galvanization is the process of applying a protective zinc coating to steel forging, to prevent rusting. The most common method is hot-dip galvanizing, in which parts are submerged in a bath of molten zinc. There are two types of zinc used, one is trivalent zinc and the other is hexavalent zinc.

Q: How to check the quality of stainless steel pipe?

A: Visual Inspection: Examine the pipe for any visible defects such as cracks, dents, or surface irregularities.
Dimensional Inspection: Measure the pipe's outer diameter (OD), inner diameter (ID), and wall thickness using calipers or a measuring tape.
