High Strength Austenite For Additive Manufacturing

Product Number: 51322-17496-SG

Author: Dr. Andreas Mohr, Dr. Horst Hill, Dipl.-Ing. Karlheinz P.J. Hoeren, M.sc. Janosch Conrads

Publication Date: 2022

Typical austenitic stainless steels like 316L (S31603) contain chromium, nickel, and, optionally, molybdenum as major alloying elements. These are required to provide their beneficial properties, which include e.g. very high corrosion resistance and high ductility and toughness, yet showing comparably low strength and hardness. General corrosion resistance is primarily achieved by the element chromium, which causes formation of a thin but dense chromium oxide layer on the surface, when the amount of chromium dissolved in the metallic matrix is larger than approximately 10.5 wt%.

Influence of Repeated Welding Thermal Cycle on The Mechanical Properties of SA516 Steel Weldment

Product Number: MPWT19-14345

Author: Sandeep Kumar, Abdulla Ali Juma

$0.00

This study investigates the influence of thermal cycle as a result of repeated welding heat input on the mechanical and microstructural properties of the SA516 Gr 65 steel plates weldment in as-welded condition. The test specimens used were having an identical joint design, welded with submerged arc welding (SAW) process. Three different heat inputs of 0.96kJ/mm (low heat input), 1.5kJ/mm (medium heat input) and 3.58 kJ/mm (high heat input) were used for welding three individual specimens. All weld longitudinal tensile testing, Charpy V-notch impact test and weld metal & heat affected zone (HAZ) microstructural testing were done. The work shows that low heat input (LHI) produced welds with highest yield, tensile strength and toughness in the weld metal whereas high heat input (HHI) resulted in decrease in yield, tensile strength and toughness in the weld metal. Increased level of acicular ferrite and a fine grain structure in weldment were achieved with LHI, while the HHI produced coarse grain structure in the weldment and in the HAZ.

Influence Of Thermomechanical Processing On Mechanical Properties And Corrosion Resistance Of Super Duplex Stainless Steel UNS S32750.

Product Number: 51322-17613-SG

Duplex stainless steels (DSSs) are based on the Fe-Cr-Ni system and are constituted of 30 to 70 % ferrite and austenite. They combine high tensile strength, good toughness, weldability, and excellent corrosion resistance including stress-corrosion cracking and resistance to localized corrosion.^1-3 DSSs can be classified according to the Pitting Resistance Equivalent Number (PREN = Cr + 3.3 Mo + 16 N) in lean duplex (PREN= 22-27), standard (PREN = 28-38), super duplex (PREN = 38-45) and hyperduplex (PREN > 45).

AM brings significant benefits in better performance, inventory management, and lifecycle cost reduction to the Oil & Gas industry. Both manufacturers and users are working towards AM qualification and standardization in order to realize and sustain these benefits. Starting at the product level, the goal is to ensure the product is sound in its form, fit, and function, and free from macroscopic (surface, sub-surface, internal) anomalies deleterious to its performance. Product qualification is supported by a foundational metallurgical or AM material qualification.¹

Mechanical Performance of Nano-Particles Enriched Zinc Rich Coatings

Product Number: 51219-189-SG

Author: Saiada Fuadi Fancy, Md Ahsan Sabbir, Kingsley Lau

Publication Date: 2019

$20.00

Corrosion is a durability concern for any unprotected structural steel from its exposure environment and coatings are widely used for corrosion protection. Zinc-rich primer-based three-coat (ZRP) systems are the most widely used for structural steel, since 1980’s. However, these coating systems often require regular maintenance. So, there is always interest to develop durable novel coating systems to reduce the maintenance cost.

Susceptibility of martensitic stainless steels to hydrogen embrittlement

Product Number: 51323-19273-SG

Author: Lütfi Ekmekci, Merlin Seifert, Clara Herrera

Publication Date: 2023

$20.00

A decarbonized energy system is underway worldwide. The Paris Agreement goal is to keep global warming “below 2 degrees Celsius above preindustrial levels, and to pursue effort to limit the temperature increase even further to 1.5 degrees Celsius.” To achieve this long-term temperature goal, big changes are needed in the ways energy is produced, distributed and storage.

Susceptibility to Hydrogen Embrittlement of Engineering Steels with Martensitic Microstructures

Product Number: 51324-20800-SG

Hydrogen emerged as a solution to increasing environmental problems and is becoming an important energy resource. However, hydrogen can deteriorate the mechanical performance of metallic components. This phenomenon is known as hydrogen embrittlement (HE). Engineering steels, such as nickel-chromium-molybdenum steels, are widely used in the industry and can be attractive materials for hydrogen applications such as pressure vessels, owing to a good combination of tensile strength (up to 1.1 GPa) and ductility (e.g., 10 % or higher). They can decrease product weight and reduce construction costs. However, as HE susceptibility tends to increase with increasing strength of steels, high-strength steels are susceptible to HE when used in hydrogen gas environment. The aim of this paper is to investigate the susceptibility of different engineering steels to hydrogen embrittlement. Three martensitic Cr-Ni-Mo steels were investigated. Slow strain rate tests were performed in gaseous hydrogen at 100 bar (10 MPa) and room temperature. Microstructure characterization and fractography study were carried out. Ni-Cr-Mo steels show a martensitic microstructure with precipitates in quenched and tempered condition. Their YS and UTS are higher than 1000 MPa (145 ksi) and 1100 MPa (159 ksi), respectively. Hydrogen gas degrades the ductility of Cr-Ni-Mo steels considerably, while strength deteriorates slightly. Fractography is characterized by a brittle fracture assisted by hydrogen. Hydrogen-Enhanced Localized Plasticity (HELP) is seen to be the primary failure mechanism in martensitic steels.

Sustainable Activated Zinc Rich Epoxy Primers with Extended Durability

Product Number: MECC23-20257-SG

Author: Santiago Arias; Jose Fernandes; Raquel Morales; Munzir Khan

Publication Date: 2023

$20.00

Zinc rich primers, both organic and in-organic coatings, are extensively used in the marine and offshore industry. The beneficial effect of zinc-rich primer on the longevity of protective coatings is primarily assumed to be due to a cathodic protection mechanism. During the 60’s and the 70’s zinc rich epoxy primers dominated the market.
