1, corrosion resistance   

Most stainless steel products require good corrosion resistance.  Stainless steel pipes similar to class I and II cutlery, kitchen appliances, water heaters, water dispensers, etc.  Some foreign merchants also test the product for corrosion resistance: use NACL aqueous solution to warm to boiling, after a period of time the solution is to drain, wash and dry, determine weight loss to determine the degree of corrosion.
 
 2. Welding machinability  

Welding performance requirements vary from product to product.  A tableware usually does not require welding properties, even for some pot enterprises.  However, most products require raw materials with good welding performance, such as class II tableware, thermos cups, steel pipes, water heaters, drinking machines and so on.
 
 3, polishing
 

At present, stainless steel products are generally polished in the production process, only a few products such as water heaters, water dispensers lining do not need to be polished.  Therefore, this requires good polishing properties of the raw material.   

The polishing performance is affected for the following three reasons:
 
 (1) There are problems on the surface of raw materials: scratches, damage, immersion, etc.;   (2) Stainless steel pipe raw material hardness is low, BQ is not good, deep drawing is prone to orange peel phenomenon, affecting the BQ performance of continuous square steel pipe, high hardness will be better.   (3) Black spots may appear on the surface of the stainless steel tube after deep drawing, which affects the BQ attribute of the stainless steel tube.

When buying stainless steel products, authenticity, processing precision, and after-sales service are the key factory
When buying stainless steel products, authenticity, processing precision, and after-sales service are the key factory
In the price-competitive environment of the stainless steel industry, many buyers treat unit price as the sole criterion for selection, ultimately falling into the trap of "low-cost procurement followed by high-cost rework." In reality, as a fundamental industrial material, stainless steel incurs costs throughout the entire lifecycle—from procurement and processing to operation and maintenance. Three key factors—material authenticity, processing precision, and after-sales service—are far more valuable than simply achieving low purchase prices.  Material authenticity is the minimum requirement when purchasing stainless steel, and also a common target for low-price traps. Some low-cost suppliers on the market often pass off inferior materials as high-quality ones—using 201 instead of 304, ordinary 304 instead of 316L, or recycled materials with non-standard thickness and subpar composition. Although these materials may appear only slightly cheaper, they can lead to premature corrosion, insufficient strength, and other issues during use, potentially causing safety incidents in chemical or food processing environments. Reputable, physical suppliers provide material quality certificates with each shipment and support spectral testing for verification, ensuring complete consistency in material composition and grade from the source.  Processing accuracy directly determines the yield rate and schedule of downstream operations. In stainless steel processing stages such as leveling, slitting, and cutting, there are clear industry standards for dimensional tolerances, flatness, and burr control. Low-cost processing often involves outdated equipment and lax quality control, resulting in excessive slit width tolerances, warped or uneven leveled sheets, and excessive burrs on cut edges. These issues can increase scrap rates in subsequent sheet metal and stamping processes, and even delay overall project timelines due to dimensional mismatches. Although high-precision processing has a slightly higher unit price, it significantly reduces rework and waste downstream, ultimately leading to lower overall costs.  Reliable after-sales service is a crucial guarantee for long-term and stable procurement. Low-cost suppliers often lack service capabilities; when issues such as material discrepancies or dimensional deviations arise, they tend to shirk responsibility and delay responses. Some small-scale vendors even lack established after-sales channels, making it difficult to hold them accountable for quality problems. In contrast, trustworthy manufacturing factories offer end-to-end support services, including product selection consultation, order tracking, handling of abnormalities, and timely replacement or reshipment, all backed by clear response mechanisms that significantly reduce buyers' communication and time costs.  From a total lifecycle cost perspective, pursuing low prices alone often proves counterproductive. Low-quality materials at lower prices may have a service life only one-third that of qualified products. When combined with hidden costs such as rework, production downtime, and equipment replacement, the overall expenditure can far exceed the cost of purchasing standard-quality materials. Procurement calculations should not focus solely on unit purchase price, but must also consider the comprehensive investment in material lifespan, processing losses, and operational maintenance costs.  The essence of stainless steel procurement lies in selecting reliable long-term suppliers, rather than simply opting for the lowest single price. By balancing cost and quality, and prioritizing material grade, precision, and service, true cost reduction and efficiency improvement can be achieved, ensuring stable progress in production and projects.
