Titanium is classified into three types in terms of materials science: α titanium, α+β titanium, and β titanium. Pure titanium has an α phase, and there are alloys that possess α phase, α+β phase, and β phase. Maruemu Manufacturing has successfully commercialized β-type titanium (Ti15-3-3-3) screws that have strength equivalent to the more expensive α+β titanium (Ti6Al-4V), achieving cost reduction.

Most of the titanium circulating in the general market is pure titanium, which does not meet satisfactory strength requirements, leading to limited applications as fastening components and necessitating an increase in the number of parts used. On the other hand, high-strength α+β type titanium alloys (Ti6Al-4V) have been adopted in some markets, but the α+β type, being difficult to process, is produced through hot forging and machining, making it hard to achieve satisfactory costs. Therefore, through unique manufacturing technology for β type titanium alloy (Ti 15-3-3-3) that has strength equivalent to α+β type, we have successfully achieved continuous forging mass production and realized cost reduction.

The "M Coat" treatment refers to a Teflon-based lubricant film treatment developed by Maruemu Manufacturing Co., Ltd. as a measure to prevent seizing of stainless steel bolts and nuts. Tests conducted on stainless steel bolts and nuts treated with "M Coat" under conditions prone to seizing (3° wedge) showed that they could be tightened without seizing. Even after five repeated tightenings, no seizing phenomenon occurred, and no abnormal "galling" was observed on the threads of either the bolts or nuts.

Seawater utilization devices, marine structures, and food machinery have all adopted various types of stainless steel to combat salt damage, as well as in environments with chlorine, such as hot water pools and septic tanks. However, conventional stainless steels are prone to localized corrosion in solutions containing chloride ions, such as seawater, and in chlorine environments, which limits their use and necessitates frequent maintenance. MS-270 is an austenitic stainless steel that offers superior resistance to chloride corrosion and stress corrosion cracking compared to SUS316 and duplex stainless steels. By adding molybdenum, nitrogen, and copper to high chromium and high nickel, MS-270 significantly enhances corrosion resistance. In addition to its resistance to chloride corrosion, it also excels in acid resistance. MS-270 makes maintenance-free operation possible. ● For other functions and details, please refer to the catalog.

We have developed a high-performance ferritic stainless steel "SF-160+α" that achieves corrosion resistance and workability comparable to general-purpose austenitic stainless steels, widely applicable for general uses. SF-160+α offers economic benefits by being free of nickel and molybdenum, along with ferromagnetic properties, low thermal expansion, oxidation resistance, and advanced refining techniques that reduce harmful impurities and inclusions. By adding trace amounts of Cu and Nb, which are effective in enhancing corrosion resistance, it achieves corrosion resistance similar to austenitic stainless steel (SUS304 series). SF-160+α not only contributes to the VA activities of customers using austenitic stainless steel but also facilitates the transition from ordinary steel plated products, providing solutions for a wide range of applications. ● For more features and details, please download the catalog.

"TWO LOCK M's" is a screw that incorporates a TWO LOCK washer. Compared to conventional spring washers, it has a wave-shaped design, which provides a greater spring reaction force and makes it more resistant to loosening. Additionally, its unique shape minimizes the biting into the counterpart material during tightening, making it less likely to cause damage. The washer's low height also means that less tightening force is required. As a result, the screw can be shorter and lighter. We have developed and commercialized this steel TWO LOCK with its advantages intact, using stainless materials that are resistant to rust. ● For other functions and details, please download the catalog.

FAMCON is constructed from three geometric features. The first feature is that the thread angle is set to 55° and the head-side flank angle to 15°, while the opposite flank angle is set to 40° with an unequal angle thread, in order to increase pull-out resistance without reducing thread strength. The second feature is the arrangement of U-shaped notches along the entire length of the threaded section to enhance screw-in capability. The third feature is that the notched part of the thread creates a recessed area at the bottom of the thread valley to serve as a collection point for the shavings produced during machining. The synergistic effect of these three features enables perfect fastening and smooth operability. ● For other functions and details, please download the catalog.

The specific gravity of magnesium is two-thirds that of aluminum and one-fourth that of stainless steel, making it the lightest metal among practical metals used as structural materials. Its alloys excel in specific strength, electromagnetic shielding properties, and vibration absorption, and are suitable for fastening magnesium alloy housings, as they do not cause galvanic corrosion when in contact with magnesium alloys. This makes them applicable in a wide range of fields, including information technology, home appliances, automobiles, and aircraft. A new history of magnesium alloys begins here.
