2. High quality carbon structural steel: steel number is expressed by the average mass thousandth fraction of carbon element content. Such as 20#, 45#, etc. Application: Mainly used for manufacturing various machine parts.
3. Carbon tool steel: steel grade is expressed by the average mass thousandth fraction of carbon element content, and preceded by T. Such as T9, T12, etc. Purpose: Mainly used for manufacturing various cutting tools, molds, measuring tools, etc.
4. Cast steel: Cast steel number is preceded by ZG. Purpose: Mainly used for manufacturing parts with complex shape and need certain strength, plasticity and toughness, such as gears, couplings, ect.
ABB strengthens ship automation and control systems
ABB recently reported that 2011 was a successful year and successfully strengthened its leading position in the market.
To better address the needs of the marine automation and control systems market, ABB has formed a new global ship information and control organization. Based on ABB's original proven process automation technology, the agency will further develop the corresponding solutions for the application of automation technology in the marine industry.
ABB's new marine automation and control system solutions include extensive ship consulting and fleet management reporting solutions, integrated automation, ship management and control systems, marine instrumentation and sensing devices. These solutions optimize vessel operation and performance, improve energy efficiency, and reliability and operational safety of onboard equipment operations.
As the demand for ship information and control systems upgrades increases, ship operators must be prepared to respond to new environmental requirements while ensuring reduced energy and fuel consumption. ABB's automation and control technologies can help address and meet these demands while reducing operating costs.
ABB's cutting-edge automation solutions have successfully helped customers improve operational efficiency and energy efficiency throughout the process industry, increasing asset availability and comprehensive safety. Applying these technologies, ABB will further develop more targeted solutions for the marine industry to meet the needs of offshore engineering vessels and merchant marine applications.
Veli-Matti Reinikkala, head of ABB's process automation business, said, "As the world's leading supplier of power and electric propulsion systems for offshore engineering drilling vessels, passenger ships, LNG carriers and other markets, ABB must not only maintain its original position, but also Building on ship automation and consulting systems products and operations based on solid industry experience and leading technology. This is a key step in achieving our growth strategy for 2015. ABB's extensive experience in process automation technology has enabled us to succeed in these industries. The proven solution has been re-allocated to benefit our marine industry customers."
As environmental regulations become more stringent, ship operators' demand for efficient ship information and control systems will grow to achieve more efficient energy efficiency and lower fuel consumption – these are areas where ABB's expertise is.
ABB has more than 3,000 installed ship automation and control systems worldwide. Experts from 22 ABB's global ship service centers are responsible for maintaining these systems and providing any required support services.
In 2011, the company sold 350 automation, ship management and control systems for different ship types including drilling vessels, jack-up rigs, offshore engineering vessels and passenger ships.
