Surface treatment of UNS S41000 stainless steel polished pipe
Leave a message
410 stainless steel polished tube is a popular choice in the industrial field! Today, let's analyze why 410 stainless steel tube is popular and the surface treatment that 410 stainless steel decorative tube can provide.
410 stainless steel tube is a high-hardness alloy with good strength, hardness and wear resistance. Compared with some high-alloy stainless steels (such as 304 and 316 stainless steel), the cost of 410 stainless steel is relatively low. This makes 410 stainless steel an economical choice to meet performance requirements under limited budgets.
In the construction industry, 410 stainless steel decorative tubes are often used to make various supporting structures, such as stair handrails, balcony guardrails, etc. These parts not only bear the weight of the human body and minor collisions in daily use, but also require good aesthetics.
The high hardness and non-rust characteristics of 410 stainless steel make it an ideal choice, which not only ensures the stability of the structure but also has a decorative effect.
In the automotive industry, due to its low density and sufficient strength characteristics, 410 stainless steel wear-resistant tubes can be effectively used in the body structure, thereby reducing the weight of the vehicle without sacrificing safety. It can also improve the handling performance and ride comfort of the car to a certain extent.
GNEE provides surface treatment for 410 stainless steel pipes including
The surface treatment of 410 stainless steel polished pipes mainly includes the following methods:
410 mechanical polished pipes: polished step by step by mechanical means such as cloth wheels and sanding belts until the surface is as smooth as a mirror. This method is suitable for large diameter pipes.
410 chemically treated pipes: including pickling, alkali washing, electrolytic polishing, passivation and anodizing. By soaking in a specific solution, a dense oxide scale or conversion film is formed to improve the performance and appearance of the stainless steel surface.
410 electrochemical polished pipes: use electrolytic polishing equipment to apply current in the electrolyte to remove tiny particles, oxide layers and stains on the metal surface, making the surface smoother and brighter.
410 protective pipes: apply a transparent protective layer on the surface, such as anti-fingerprint coating, to prevent fingerprints, scratches, and extend the service life.

Inspection Standards
We strictly adhere to industry standards for quality inspection, including:
* Surface Quality Inspection: Surface roughness is measured using advanced equipment to ensure a smooth, flawless surface. The polished pipe surface achieves a finish of Ra ≤ 0.4 μm, and all surface defects are removed through visual inspection and precision instrument testing.
Dimensional Inspection: The outer diameter, wall thickness, and other dimensions of each pipe are checked using precision measuring tools and automated testing equipment to ensure compliance with customer requirements.
Delivery Time
Our typical delivery time is as follows:
Standard Products (Common Sizes, Surface Treatments): Delivery time is 7 to 15 working days, depending on stock availability and order quantity.
Customized products (special sizes, surface treatments): delivery time is 20 to 30 working days, depending on the customization requirements and production schedule.
Packaging and Transportation
Our packaging design aims to ensure the pipes are not damaged during transportation while minimizing external contamination:
* Packaging: Each batch of pipes is customized according to different sizes. Common packaging methods include wooden crates, wooden pallets, plastic film, and moisture-proof materials. For large orders, we also offer container shipping solutions to ensure the stability of the goods.
