Mendeleev
Q. How do Chemists change the periodic table over time?
The periodic table has long-since filled in Mendeleev’s gaps and has added new elements. It has even changed the weights of other elements. The periodic table is continually being changed as new discoveries are made and new theories are developed to explain the behavior of chemicals.

GENERIC METAL PRICES
| ITEM | PRICE |
|---|---|
| Clean Aluminium | $1.00 – $1.50 per kilo |
| Stainless Steel (all types) | $1.00 – $1.50 per kilo |
| Lead | $1.50 – $2.00 per kilo |
| Steel | $100 – $300 per tonne |
Q. What is the price of stainless steel per kg?
Stainless Steel 304 Price Per Kg
| Stainless Steel 304 price per kg | Origin | Price in INR (per kg) |
|---|---|---|
| SS 304 price per kg in India | Indian | Rs 195/- |
| SS 304 price per kg in Japan | Japanese | Rs 250/- |
| SS 304 price per kg in UK / Europe | European | Rs 300/- |
| SS 304 price per kg in USA | USA | Rs 350/- |
Q. Which is stronger 304 or 316 SS?
Though the stainless steel 304 alloy has a higher melting point, grade 316 has a better resistance to chemicals and chlorides (like salt) than grade 304 stainless steel. When it comes to applications with chlorinated solutions or exposure to salt, grade 316 stainless steel is considered superior.
Q. What is the hardest grade of stainless steel?
440C stainless steel
Q. What is the cheapest grade of stainless steel?
Type 409: One of the least expensive Stainless grades due to its decreased chromium content. This type should only be used for interior or exterior parts in non-critical corrosive environments. Typical applications include muffler stock.
Q. What type of steel is 18-8?
Stainless Steel
Q. Which is stronger 18-8 or 316 stainless steel?
The 316 stainless steels have 2-3% molybdenum added while the 18-8 series stainless steels do not. While it has comparable strength characteristics, 316 and 316L stainless steel have a higher degree of corrosion resistance due to the addition of the element molybdenum.
Q. Is Grade 5 stronger than stainless steel?
The hardest standard stainless steel is X30CrMoVN15-1 and can be quenched and tempered. It can reach more than 2000 N/mm². It is stronger than titanium grade 5. However it is a bearings steel and is not used in standard bolts.
Q. What is Grade 5 steel?
Grade 5 alloy steel is a medium carbon zinc plated alloy steel that is heat treated to increase hardness. Grade 5 bolts have three (3) evenly spaced hash marks on the head markings (manufacturers mark may also be included).
Q. What is the strongest metal for bolts?
The strongest commercial-quality bolt is grade 8, marked by six raised dashes; its medium-carbon alloy steel has been quenched and tempered to achieve a tensile strength of 150,000 psi.
Q. How strong is Grade 5 steel?
Bolt Grade Markings and Strength Chart
| Head Marking | Grade and Material | Mechanical Properties |
|---|---|---|
| Min. Tensile Strength (psi) | ||
| 3 Radial Lines | Grade 5 Medium carbon steel, quenched and tempered | 120,000 |
| 105,000 | ||
| 6 Radial Lines | Grade 8 Medium carbon alloy steel, quenched and tempered | 150,000 |
Q. Is grade C the same as Grade 5?
Because there are so many different grades and fasteners all look about the same, medium carbon and alloy steel strength grades are marked for identification….Table 1.
| Grade/Class | Strength |
|---|---|
| Grade C Nuts | Strength exceeds Grade 5. Use with heat-treated medium-strength steel fasteners like ASTM A325 structural bolts. |
Q. Is stainless steel or grade 8 stronger?
Stainless Steel Grades & Strength Stainless commonly comes in grades 18.8 (304) or T316. Stainless steel bolts are rated for corrosion resistance. A stainless steel bolt has the same PSI rating as a grade 5 bolt (125,000 PSI). A grade 8 bolt has a stronger rating with a PSI of 150,000.
