We would like to introduce the "austenitic stainless steel (SUS304 and others)" that we handle. "SUS304" is a representative grade of austenitic stainless steel, suitable for applications such as utensils, kitchens, and LNG tanks. Additionally, "SUS301" possesses characteristics that allow for high strength through heat treatment rolling, making it suitable for applications such as steel belts, metal gaskets, and springs. Our company supports you with a rich inventory of special steels (SC/SK/SUP/SCR/SCM), stainless steels (SUS/HT1770), processing know-how, and material procurement both domestically and internationally (Japan/Thailand/China), as well as procurement of processed products. 【Steel Grades (Partial)】 ■SUS301 ■SUS301L ■SUS304 ■NSS304S ■NSS304ES *For more details, please download the PDF or feel free to contact us.

We would like to introduce the "ferritic stainless steel (SUS430 and others)" that we handle. "SUS430" is a representative grade of ferritic stainless steel, known for its excellent corrosion resistance, and can be used for oxidation-resistant parts at temperatures below 850°C. Additionally, we also handle "NSS430M2," which has better workability and corrosion resistance than SUS430, and "NSS430M4," which has superior workability, weldability, and corrosion resistance compared to SUS430. Our company supports you with a rich inventory of special steels (SC/SK/SUP/SCR/SCM), stainless steels (SUS/HT1770), processing know-how, and material procurement both domestically and internationally (Japan/Thailand/China). 【Characteristics】 ■SUS430: A representative grade of ferritic stainless steel, excellent corrosion resistance, used for oxidation-resistant parts below 850°C. ■NSS430M2: An improved version of SUS430 with added Ti, offering better workability and corrosion resistance. ■NSS430M4: An improved version of SUS430 with added Nb, providing superior workability, weldability, and corrosion resistance. *For more details, please download the PDF or feel free to contact us.

We would like to introduce the "martensitic stainless steel (SUS420J2 and others)" that we handle. "SUS420J2" has the characteristics of high hardenability and work hardening, making it suitable for table knives, calipers, rulers, scissors, and more. Additionally, "SUS410" is a representative 13Cr stainless steel with low hardenability, suitable for applications such as turbine blades, spoons, and forks. Our company supports you with a rich inventory of special steels (SC/SK/SUP/SCR/SCM), stainless steels (SUS/HT1770), processing know-how, and material procurement both domestically and internationally (Japan/Thailand/China), as well as procurement of processed products. 【Steel Types (Partial)】 ■SUS403 ■SUS410 ■SUS410S ■NSS410M4 ■NSS410M5 *For more details, please download the PDF or feel free to contact us.

We would like to introduce the "duplex stainless steel (SUS329J1 and others)" that we handle. "Lean duplex steel" is a low-cost type with low nickel content and minimal molybdenum, making it suitable for civil engineering, construction, industrial machinery, storage tanks, and more. In addition, we also handle "general-purpose duplex steel," which has excellent resistance to seawater corrosion, and "super duplex steel," which has corrosion resistance comparable to super austenitic steel. Our company supports you with a rich inventory of special steel (SC/SK/SUP/SCR/SCM) and stainless steel (SUS/HT1770), processing know-how, and material procurement both domestically and internationally (Japan/Thailand/China), as well as procurement of processed products. 【Characteristics】 ■ Lean duplex steel: A low-cost type with low nickel content and minimal molybdenum, beneficial for replacing SUS304 and SUS316 series with duplex steel. ■ General-purpose duplex steel: Excellent resistance to seawater corrosion. ■ Super duplex steel: Has corrosion resistance comparable to super austenitic steel. *For more details, please download the PDF or feel free to contact us.

We would like to introduce the "precipitation hardening stainless steel (HT1770, SUS630, etc.)" that we handle. "HT1770" is a stainless steel (precipitation hardening steel) that exhibits excellent spring characteristics, with significant hardening due to aging treatment, allowing for punching processing at low hardness. Additionally, we also handle "HT980," which achieves high strength through quenching at temperatures above 750°C, and "HT1770M," which combines high toughness, high strength, and high fatigue resistance. Our company supports you with a rich inventory of special steels (SC/SK/SUP/SCR/SCM) and stainless steels (SUS/HT1770), processing know-how, and material procurement both domestically and internationally (Japan/Thailand/China), as well as procurement of processed products. 【Characteristics】 ■ NSSHT980: High strength is obtained through quenching at temperatures above 750°C ■ NSSHT1770: Significant hardening due to aging treatment allows for punching processing at low hardness ■ NSSHT1770M: High toughness, high strength, and high fatigue resistance achieved through Mo addition ■ NSSHT2000: Among stainless steels, it exhibits high strength as well as excellent toughness and fatigue characteristics *For more details, please download the PDF or feel free to contact us.
