Manufacturers typically produce hose clamps using materials like 201 or 301 stainless steel, while 304 stainless steel serves as the food-grade option due to its superior corrosion resistance.Different materials result in significant price differences. If you place 201 and 301 stainless steel hose clamps side by side, you cannot tell them apart at a glance. Next, Our Company will introduce a method to distinguish their materials as follows.

Take American-style stainless steel hose clamps as an example. Drop the solution on the surface: if it turns brick red, the material is 201. If it does not change color, the nickel content of the material is higher than 6%, and at this point, you can judge that it may be either 301 or 304. To further distinguish between 301 and 304, you need to perform an electrolysis test with a 9V battery. After 6 seconds of electrolysis, if a light red color appears, the material of the stainless steel hose clamp is 301. If no color change occurs, the material is 304.
Manufacturers classify stainless steel hose clamp materials based on their nickel content, typically producing these clamps from grades such as 201, 301, or 304 stainless steel for varied applications. Among these options, type 304 qualifies as food-grade due to its excellent corrosion resistance. Material selection greatly influences cost, creating noticeable price differences across types. Interestingly, clamps made from 201 and 301 appear nearly identical upon visual inspection. To help distinguish them effectively, we will now introduce a reliable identification method based on material properties.
These clamps are typically crafted from durable materials such as 201, 301, or 304 grades, with 304 being preferred for food-grade applications owing to its exceptional corrosion resistance. Material selection significantly impacts pricing, though 201 and 301 variants may look indistinguishable visually. Below, we outline a practical method to distinguish their compositions with precision.
