해양 등급 316 스테인레스 스틸 직사각형 중공 단면 용접 ASTM A554
Marine grade rectangular hollow section (RHS) refers to 316 stainless steel rectangular tubing specifically designed for applications in coastal, offshore, and marine environments where standard 304 stainless steel would be susceptible to pitting and corrosion from chloride exposure. The addition of 2-3% molybdenum to the 316 grade provides significantly enhanced resistance to pitting, crevice corrosion, and stress corrosion cracking in seawater, salt spray, and chloride-rich
316 스테인리스 스틸 직사각형 튜브 ASTM A554 직사각형 홀 섹션
316 stainless steel rectangular tubing is the premium choice for applications requiring superior corrosion resistance, especially in chloride-rich environments such as coastal areas, marine settings, and chemical processing facilities. The addition of molybdenum (2-3%) gives 316 significantly better resistance to pitting, crevice corrosion, and stress corrosion cracking compared to 304 stainless steel. This rectangular hollow section (RHS) is manufactured to ASTM A554
ASTM B407 UNS N08810 인콜로이 800H 파이프 고온 서비스 합금
UNS N08810 고온 서비스 합금 ASTM B407
고강성 인코넬 625 UNS N06625 합금
UNS N06625 is a nickel-chromium-molybdenum alloy with outstanding corrosion resistance and high strength over a broad temperature range from cryogenic to 980°C (1800°F). The addition of niobium (columbium) and tantalum provides exceptional resistance to pitting, crevice corrosion, and chloride ion stress-corrosion cracking. Unlike many high-temperature alloys, UNS N06625 does not rely on precipitation hardening for strength. Instead, it derives its high tensile and creep
높은 온도 크립 저항 인콜로이 800HT 튜브 UNS N08811 니켈 철 크롬 합금
UNS N08811 is a nickel-iron-chromium alloy specifically designed for high-temperature service with exceptional creep and rupture strength. It is a controlled chemistry version of UNS N08800 (Alloy 800), with tighter limits on carbon (0.06-0.10%), aluminum (0.15-0.60%), and titanium (0.15-0.60%) to optimize high-temperature performance. The alloy maintains an austenitic structure and offers excellent oxidation and carburization resistance, as well as good corrosion resistance
