Duplex Stainless Tubes:
ASTM A789 (ASME SA789) General purpose seamless and welded ferritic/austenitic stainless steel pipe
ASTM A790 (ASME SA790) Seamless and welded ferritic/austenitic stainless steel nominal pipe
GB/T 21833-2008 Austenitic - ferrite grades duplex stainless steel seamless steel tube
Duplex stainless steel tube/super duplex stainless steel tube is composed by and phrase organization of
the austenitic and ferritic about half and half of the proportion. For It possessed both austenite and ferrite
stainless steel characteristics, so it owns high strength and corrosion resistance of stainless steel. Usually,
in the case of low carbon content of C, Cr content is about 18% ~ 28%, Ni content is about 3%-10%, Some
steel contain Mo, Cu, Nb, Ti, N and other alloy elements.Compared with ferrite, plasticity and toughness is higher
, there is no room temperature brittleness, intergranular corrosion resistance and welding performance were
significantly increased, while maintaining a ferritic stainless steel of 475 ℃ brittleness and high thermal conductivity,
it has the characteristic of superplasticity. Compared with austenitic stainless steel, the yield strength increased
significantly, the resistance to intergranular corrosion, stress corrosion and corrosion fatigue and abrasion
performance improved significantly.

Toyota’s innovative spirit extends far beyond its iconic vehicles, surprising many with the variety of products it creates that don’t rely on four wheels. Here are seven unexpected items from Toyota that might just blow your mind.
First up, houses. Yes, you read that right. Since 1975, Toyota has been constructing homes using an assembly line approach. Initially, dealerships offered housing plans as part of their services to enhance the quality of Japanese homes. Over the years, Toyota has built close to 250,000 homes, expanding its offerings to include condos, mortgages, and even temporary shelters for earthquake victims in Turkey. The company ensures environmental sustainability through three key principles: developing eco-friendly products, using materials that reduce carbon emissions, and ensuring each home lasts at least 30 years. A new Toyota house starts at $200,000, with upgrades pushing the price up to $800,000.
Next, Toyota ventured into the boating world. Between 1998 and 2001, Toyota introduced its Epic boats globally, starting with the 21-foot closed bow ski boat. While initially successful, sales dipped, leading to the closure of a 70,000-square-foot facility complete with a ski lake in 2001. However, Toyota made a comeback in 2014 with the Ponam-31, a "sport utility" boat designed for cruising, fishing, and leisure. Features include a U-shaped sofa for card games, two driving areas, and engines borrowed from the Land Cruiser Prado. Prices start around $275,000.
Then there are robots—adorable ones at that. Inspired by the original Kirobo robot sent to the International Space Station, Kirobo Mini is a pint-sized companion robot that can read emotions, engage in small talk (in Japanese), and practically begs you to take it along. Standing at just 4 inches tall, this mini robot could be the perfect travel buddy.
In addition to robots and boats, Toyota has dabbled in public transportation with its Dual Mode Vehicle, essentially a microbus that transforms from a car to a train. This hybrid vehicle was used in Japan's public transit system and features both rubber tires for roads and steel wheels for tracks.
Perhaps less known is Toyota’s contribution to technology with QR codes. A Toyota subsidiary created the Quick Response (QR) code in 1994, initially intended for managing automotive components. With the rise of smartphones, QR codes have become ubiquitous, connecting people to information instantly.
Speaking of practical innovations, Toyota has been making sewing machines since 1945. Their Home Sewing website offers some of the most functional sewing machines available. Despite being a well-kept secret in the U.S., these machines are highly regarded worldwide.
Lastly, Toyota produces some of the most advanced forklifts and pallet trucks globally. Countries like France, Sweden, and Italy manufacture these industrial vehicles, equipped with cutting-edge technologies such as Toyota’s System of Active Stability. These forklifts are more than just work tools—they’re precision machines designed for efficiency and safety.
So, if you could choose any non-car Toyota product to own, what would it be? Let us know on Facebook!
And remember, Toyota’s creativity doesn’t stop at cars—it’s a company that thinks outside the box, proving that innovation truly knows no bounds.
