1. Conventional menu

Applicable vessel types	Products	Features
General	◎AH32, DH32, EH32 AH36, DH36, EH36 AH40, DH40, EH40	●Strength and base metal toughness with low Ceq contents are ensured by using TMCP ●High heat input and high HAZ toughness by using Ti
Gas carriers	◎KL24, KL27 KL33, KL37 (Including materials equivalent to other classifications)	●Low carbon content, reduction of impurity elements ⇒Ensuring high heat input and HAZ toughness at low temperatures such as around -60°C

2. Our recent unique menu

Applicable vessel types	Products		Features
Multi-purpose Gas Carriers	◎Ammonia SCC resistance Low-temperature デュエルビッツ登録es Application for tanks and secondary barrier (Equivalent to KL27 and KL33)		●Ensuring base metal properties and HAZ toughness of plates with a thickness of 30 mm or less at low temperatures down to about −60°C. ●Lowering carbon content (0.05% compared to conventional steel 0.08%) to reduce the HAZ hardness →Improved ammonia stress corrosion cracking resistance ●Stable HAZ toughness Strict control of controlled rolling conditions →Stable reduction of YR (90% or less)
Large Container Ships	◎Heavy-thick デュエルビッツ登録es for High heat input welding Hatch coaming デュエルビッツ登録eer strakes	EH40 EH36	●Heavy-thick high-strength デュエルビッツ登録es, 1-pass vertical position weldable by SEGARC welding up to 65 mm thickness ●Use of TMCP at a high cooling rate with low C and low Ceq contents →Ensuring HAZ toughness in high heat input welding (Ensuring HAZ toughness at -20°C to -40°C with a welding heat input of 400 kJ/cm)	⇒The welding time can be shortened to 1/10 compared to conventional CO₂ multi-layer welding.
Large Container Ships		EH47	●Heavy-thick high-strength steel, can be ensured one-pass vertical welding by SEGARC welding up to 55 mm thickness
	◎EH36 デュエルビッツ登録e for High heat input welding Used デュエルビッツ登録eer strakes at the longitudinal center of the hull		●one-pass vertical position weldable by Electro-Gas Arc welding up to 20 mm thickness ●Low C / Low Ceq (Ensuring HAZ toughness at -40°C with a welding heat input of 250 kJ/cm)
	◎Corrosion resistant steel for bottom plate of COT “KPAC-1” Corrosion resistant steel for bottom plate of COT “KPAC-2”		●Applicable without coating
Offshore Structures	◎Grade F heavy-thick デュエルビッツ登録e		●Toughness at a temperature of -60°C can be ensured up to 90 mm thickness
General	◎Residual stress controlled デュエルビッツ登録e (Hizumi-less) (Super-Hizumi-less)		●Deformation control by bar steel longitudinal cutting, etc.
