We would like to introduce the fourth installment of the four-panel manga "Go for it!! Bobin-kun" by Nobu Sakai. Stainless steel is a type of steel that is resistant to surface corrosion in the atmosphere, underwater, and in other corrosive environments. It can be broadly classified into "iron-chromium" or "iron-chromium-nickel" alloy steels. The iron-chromium type is more prone to corrosion (rust) compared to the iron-chromium-nickel type, and if rainwater is left on it, especially in the "gaps," there is a possibility of rust forming. It is by no means "rust-proof steel," so it should be understood and used accordingly, with the selection of the steel type being very important. You can view the continuation of the four-panel manga on our company website. [Summary] - The iron-chromium type is more prone to corrosion (rust) compared to the iron-chromium-nickel type, and if rainwater is left on it, especially in the "gaps," there is a possibility of rust forming. - It is not "rust-proof steel," so it should be understood and used accordingly, with the selection of the steel type being very important. *For more details, please refer to the related links or feel free to contact us.

We would like to introduce the fourth-panel manga "Go for it!! Bobin-kun" by Nobu Sakai, <Episode 6>. When salt absorbs moisture, it behaves as a solution, and when chlorine ions react with the passive film on the stainless steel surface, it destroys the passive film. If "self-recovery" cannot keep up during this process, rust occurs. By adding about 2-3% Mo (molybdenum) to SUS304, which is a representative type of austenitic stainless steel, the "corrosion resistance" improves, providing a measure to prevent "rust formation" due to salt. You can view the continuation of the four-panel manga on our company website. [Overview] - Salt has the property of absorbing surrounding moisture and turning into a solution (hygroscopicity), so if left attached, it will absorb moisture from the surroundings and become a "cause of rust." - Selecting the appropriate type of stainless steel is very important for its use. *For more details, please refer to the related links or feel free to contact us.

In the case of titanium fine wire, our technology cannot perform drawing processing without an oxide film (black skin). By placing an oxide film (black skin) on the surface of the wire material, this film comes into contact with the diamond of the die during the drawing process, enabling the drawing process with a lubricant (oil). You can view the continuation of the four-panel manga on our company website. [Overview] - Regarding titanium drawing processing, drawing is performed after sufficiently applying an oxide film (black skin) to the surface of the wire material through atmospheric annealing (heat treatment). - As long as there is some film on the surface of the wire material, die drawing processing is possible. *For more details, please refer to the related links or feel free to contact us.

We would like to introduce the four-panel manga "Go for it!! Bobin-kun" by Nobuaki Sakai, <Episode 13>. The drawing of fine titanium wire through drawing is done using die drawing, so if there is no coating on the surface of the wire material, the drawing process itself cannot be performed. Our company does not have the equipment or technology to apply a nickel coating to the wire surface, so we adopt a method of applying an oxide coating (black scale) through atmospheric annealing (heat treatment) before the drawing process. You can view the continuation of the four-panel manga on our company website.

We would like to introduce the four-panel manga "Go for it!! Bobin-kun" by Nobu Sakai, <Episode 29>. Metals each have their own characteristics, with some being "strong" and others "weak." Stainless steel is "Stain(less) Steel," meaning it is resistant to rust, but it is not "rust-proof steel." Therefore, it is important to understand and use it as such, and selecting the appropriate steel type is crucial when using it. You can view the continuation of the four-panel manga on our company website. 【Major Categories of Stainless Steel】 ■300 Series: Austenitic ■400 Series: Ferritic/Ferritic-Austenitic/Martensitic ■600 Series: Precipitation Hardening *For more details, please refer to the related links or feel free to contact us.

We would like to introduce the four-panel manga "Go for it!! Bobin-kun" by Nobu Sakai, <Episode 30>. Not only stainless steel wire but also metal wire can be broadly classified into two categories based on "finish." There are two types: soft wire and hard wire. This is a significant difference, so naturally, when used as materials, the choice will depend on which material (property) is suitable for the intended use and processing. You can view the continuation of the four-panel manga on our company website. 【Characteristics of Soft Wire】 ■ Soft ■ Low tensile strength (breaking strength) ■ Ductile *For more details, please refer to the related links or feel free to contact us.

We would like to introduce the four-panel manga "Go for it!! Bobin-kun" <Episode 31> by Nobu Sakai. Hard drawn wire is characterized by high tensile strength (breaking strength), low elongation, and elastic (spring-like) properties. It is used in processing and applications that are suitable for these characteristics. In the case of wire materials, the typical applications are "springs" and "twisted wire (ropes)." "Springs" are used as single wires (one piece), while "twisted wire (ropes)" are made by twisting multiple wire materials together.

We would like to introduce the four-panel manga "Go for it!! Bobin-kun" by Nobu Sakai, <Episode 38>. For example, wire materials used for ropes (twisted wires) are desired to have ± (plus/minus) tolerances or + (plus) tolerances. This is because a certain breaking strength is required for ropes (twisted wires). If each individual wire that makes up the rope (twisted wire) becomes minus tolerance (thinner), the breaking strength of each individual wire decreases. As a result, the breaking strength of the finished rope (twisted wire) becomes lower, falling below the standard values for ropes (twisted wires).
