No, a wrench is just a piece of steel. Mechanical energy may be used when someone takes a bolt off with it.
Toughness
CRCA: Cold rolled close annealed,the sheet is rolled below the recrystalization temaparature of the steel,this type of sheets will have close tolerance,good finish and better mechanical strength HRCA: Hot rolled and close annealed, here the steel is rolled above the recrystalization temparature,this type of sheets have coarse finish, rough surfaces and less mechanical strength compared to CRCA

ASME SA106 refers to a standard specification developed by the American Society of Mechanical Engineers (ASME) for seamless carbon steel pipe used in high-temperature service. It is primarily used in the construction of pipelines and pressure vessels. The material is designated for applications requiring a minimum yield strength and is commonly used in industries such as oil and gas, petrochemical, and power generation. The specification outlines various grades (A, B, and C) based on the chemical composition and mechanical properties of the steel.
No he invented the Mechanical Reaper.
The steel plow and mechanical reaper revolutionized agriculture in the U.S. by significantly increasing efficiency and productivity. The steel plow allowed farmers to break tough soil more easily, facilitating the cultivation of previously challenging land. Meanwhile, the mechanical reaper enabled faster harvesting of crops, reducing labor costs and time. Together, these inventions contributed to the expansion of farming, increased crop yields, and ultimately supported the growth of the American agricultural economy.

The steel plow was one technology that settlers utilized to help them tame the prairie. Another was the mechanical reaper.

These inventions were important because farmers no longer needed to hire workers, because they had new machinery. These workers moved to bigger cities and the employees of factories increased.
John Deere inented the polished steel plow while Cyrus McCormick invented the mechanical reaper, or what most of us would call a combine nowadays.

He invented the polished steel plow which made the farmers' jobs much easier. He also set up a distribution system for his plows and other products that gave farmers quality equipmant with parts and service to back it up.
