Pickling treatment of stainless steel and titanium.

basic information

【 Product Size, Product Lot, Processing Cost 】 We can accommodate sizes from small items to large products and lots from single items to large lots. Processing costs will be estimated for each product as needed. If we are conducting welding discoloration removal in-house using burn removal agents or machines, it is often more cost-effective for us to handle the processing depending on the shape and quantity, so please inquire. 【 Applicable Materials 】 We can accommodate various steel types, starting with SUS430 and SUS304 stainless steel. Titanium is also possible. We can handle a variety of materials, so please inquire. ◇◇ Please feel free to contact us for more details ◇◇

  [Surface Treatment Case] A case where a pickling contractor was requested to reduce the cost of removing discoloration. The product in the photo has a production lot of about 40 to 50 pieces per batch, and due to its relatively small and simple structure, the manufacturer was processing it in-house using a discoloration remover. The process using the discoloration remover involves applying the remover → leaving it for (2 to 12 hours) → rinsing → brushing → washing with water → drying, which surprisingly takes a lot of time and effort. As a result, when the cost of removing discoloration was calculated, it amounted to 460 yen per piece. In contrast, the unit price when requested from our company was less than half of that. Even considering transportation costs and others, this resulted in significant cost savings, and furthermore, the entire product was uniformly finished beautifully, eliminating the need for rework in surface treatment and preventing delays in delivery.

  【Surface Treatment Example】Case of White Finish with Pickling The product in the photo is a stainless steel sheet metal part. It uses a material commonly referred to as 2B, and due to bending and welding, it had some minor scratches and oxidation scale. By applying pickling to such products, the minor scratches become less visible, and the oxidation scale from welding (burn marks) is removed, resulting in a higher quality finish for the product itself. Additionally, dirt is removed, leaving a clean, pearlescent surface (also known as pickled surface).

  【Surface Treatment Case】A Case of Removing Welding Scale While Retaining Gloss This is a treatment case that responds to the request, "I want to remove welding scale while keeping as much gloss as possible." Generally, acid pickling of stainless steel products results in a white finish, but there are times when customers request that it not become too white. In such cases, we usually recommend electropolishing; however, if the interior is partitioned into several sections or has a complex shape, electropolishing is not suitable, so we proceed with acid pickling. While it is difficult to perfectly meet this requirement, we can minimize the whitening to some extent, as shown in the photo, while removing the welding scale. Since the treatment conditions vary for each product, please contact us first.

  【Surface Treatment Example】Pickling of Titanium Containers Our company conducts pickling not only for stainless steel but also for titanium. The photo shows a sample of a titanium container that has undergone pickling. Before treatment, the surface was cloudy due to dirt accumulated during the processing stage, but after pickling, the dirt was removed, resulting in a smoother surface with a slightly whiter finish, giving it a clean appearance. As seen in this treatment example, pickling of titanium is utilized for purposes such as "removing dirt from the titanium surface."
